+++ Universum +++ - "Kepler" entdeckt zehn neue erdähnliche Planeten        
Mit dem Weltraumteleskop "Kepler" haben Wissenschaftler der US-Raumfahrtbehörde Nasa mehr als 200 mögliche neue Planeten erspäht. Von den insgesamt 219 sogenannten Exoplaneten seien 10 fast so groß wie die Erde und könnten möglicherweise die Voraussetzungen für Leben bieten.
          +++ Universum +++ - Neuer Exoplanet entdeckt: "Eiskugel" ist so schwer wie die Erde        
Ein neuentdeckter Planet ist genauso schwer wie die Erde und dreht sich im selben Abstand um seinen Stern wie unser blauer Planet um die Sonne. Bedingungen für Leben sind auf ihm jedoch nicht vorhanden.
          +++ Universum +++ - Astronomen sichten neue "Super-Erde": Ist dort Leben möglich?        
Immer wieder sorgen neue Exoplaneten für Aufregung, auf denen Leben möglich sein könnte. Jetzt legen Astronomen nach. Eine erstmals erspähte "Super-Erde" könnte sich nach Ansicht ihrer Entdecker als aussichtsreichster Ort für die Suche nach Leben jenseits unseres Sonnensystems entpuppen. Der Exoplanet kreist rund 40 Lichtjahre von unserer Erde entfernt um den roten Zwergstern LHS 1140.

At Camp Invention, almost two million students have explored their own innate creativity, inventiveness and entrepreneurial spirit in a week-long day camp program that’s been running annually since 1990. Currently held at more than 1,400 sites in 50 states for kindergarten through 6th grade, these students are learning how to think big, be innovators and pursue their dreams.

Camp Invention is a partnership between the United States Patent and Trademark Office (USPTO) and the National Inventors Hall of Fame. The program includes a robust STEM (science, technology, engineering and mathematics) curriculum while also providing insights into the role of patents and trademarks in innovation. Children develop questions, collect data, draw conclusions and apply new knowledge while tackling hands-on challenges.

Recently, I had the chance to visit Camp Invention at Hyattsville Elementary in Maryland. I was impressed by how the students came up with new product ideas and built original prototypes using real tools and components found in everyday devices. But beyond that, they had also thought through how they were going to brand and market an item and how they would protect their innovation by applying for a patent and trademark. I was inspired by their enthusiasm and inventive thinking.

Camp Invention is unique because it provides an exciting environment with no wrong answers, a chance to brainstorm with peers and an opportunity to build confidence in the natural ability to dream and create. On a given day, students might learn about such things as terraforming exoplanets, building an air cannon, exploring circuits and electronics or presenting their new invention to mock investors.  

Each year, one Camp Invention student is selected through the “Mighty Minds” contest for an all-expense paid trip to attend the National Inventors Hall of Fame Induction Ceremony in Washington, DC.  This year, the winner was 9-year-old Mya Sewell of Grayson, GA, who has attended Camp Invention for several years. She says she wants to be a scientist or inventor because, “it gives me the freedom to experiment with things without anybody telling me what to do.” Learn more about her experience interacting with prominent inventors at next year’s induction ceremony on May 4, 2018.

In addition to Camp Invention, the USPTO also works with the National Inventors Hall of Fame on the Collegiate Inventors Competition, a program designed to allow undergraduate and graduate students to showcase their emerging ideas and inventions that will shape our future. The finalists are judged by a team of inductees from the National Inventors Hall of Fame and USPTO subject-matter experts, and then honored at the USPTO. Winners enjoy over $100,000 in cash prizes and an all-expense paid trip to Washington, DC.

Through the USPTO’s partnerships with youth programs, such as Camp Invention and Collegiate Inventors, we hope to inspire future innovators and encourage creativity and problem-solving skills to enable the next generation to achieve the American Dream.

          El telescopio 'Kepler' ya no podrá buscar planetas como la Tierra por una avería

El 'cazador de planetas' ya no podrá seguir buscando mundos parecidos a la Tierra.


 La NASA ha informado de que detiene definitivamente los intentos por solucionar los fallos en el telescopio espacial 'Kepler', y que, por tanto, es imposible que continúe su misión de búsqueda de pruebas de la existencia de planetas similares a la Tierra fuera de nuestro Sistema Solar.
"Después de meses de análisis y pruebas, el equipo del telescopio espacial Kepler pone fin a sus intentos de restaurar el pleno funcionamiento del artefacto, y ahora se encuentra considerando qué posibles investigaciones puede llevar a cabo en su condición actual", informó la agencia espacial de EEUU.
En mayo pasado, la NASA informó de la detección de un "fallo" en el sistema de dirección del aparato, por el que habían perdido el control de dos de sus cuatro rotores, utilizados para estabilizar el telescopio y ajustar la dirección de sus lentes. La sonda orbita el Sol a 64.000 millones de kilómetros de la Tierra.
Los esfuerzos de los técnicos "no han tenido éxito", agregó la agencia espacial, que recordó que necesitan tres rotores para poder llevar a cabo las labores de investigación de "exoplanetas" (planetas de fuera del sistema solar).

'Descubrimientos extraordinarios'

"'Kepler' ha realizado descubrimientos extraordinarios al encontrar exoplanetas, incluidos varias super-Tierras en zona habitable. Tras saber que el Kepler ha recogido exitosamente información de su misión primordial, estoy confiado en que más descubrimientos fascinantes están en el horizonte", aseguró John Grunsfeld, director adjunto de la Misión Científica de la NASA en una nota de prensa.
El pasado 8 de agosto, los ingenieros volvieron a probar el funcionamiento del telescopio y determinaron que el rotor está estropeado, por lo que es imposible "volver al punto de exactitud que garantiza su fotometría de alta precisión".
Por ello, lo devolvieron al Modo de Seguridad de Propulsión Controlado, en el que se encuentra "seguro" pero ya no pueden manejarse sus lentes desde el centro de operaciones.
'Kepler', que vigila más de 150.000 estrellas en busca de planetas o candidatos planetas, ha sido una las misiones recientes más exitosas de la NASA. Los datos recabado por Kepler han permitido confirmar 135 exoplanetas y alrededor de 3.500 candidatos a serlo.
Fue lanzado en 2009 en busca de pruebas de la existencia de planetas similares a la Tierra o en los que se den las condiciones de temperatura medias donde pueda existir agua líquida.
Con un presupuesto de 600 millones de dólares, estaba previsto que su misión concluyera a finales de 2012, pero fue fue prolongada hace dos años hasta el 30 de septiembre de 2016.

A team of Carnegie scientists has discovered three giant planets in a binary star system composed of stellar ''twins'' that are also effectively siblings of our Sun. One star hosts two planets and the other hosts the third. The system represents the smallest-separation binary in which both stars host planets that has ever been observed. The findings, which may help explain the influence that giant planets like Jupiter have over a solar system's architecture, have been accepted for publication in The Astronomical Journal.

          Planet found in habitable zone around nearest star        

Astronomers using ESO telescopes and other facilities have found clear evidence of a planet orbiting the closest star to Earth, Proxima Centauri. The long-sought world, designated Proxima b, orbits its cool red parent star every 11 days and has a temperature suitable for liquid water to exist on its surface. This rocky world is a little more massive than the Earth and is the closest exoplanet to us -- and it may also be the closest possible abode for life outside the Solar System. A paper describing this milestone finding will be published in the journal Nature on 25 August 2016.

 1. Exoplanet Transit Campaign for IL Aqr/GJ 867


--------------------------------------------------------------------------
 1. EXOPLANET TRANSIT CAMPAIGN FOR IL AQR/GJ 867


 The AAVSO has teamed up with transitsearch.org to coordinate an observing
campaign for IL Aqr, a.k.a GJ 867 in the transit search community. Dr.
Greg Laughlin, University of California at Santa Cruz, is looking for
observations during an upcoming transit opportunity.
 IL Aqr is located at R.A.: 22:53:17  Decl.: -14:15:48 
 
 The GJ 876 system contains two planets orbiting a nearby M-dwarf star.  
The planets are in an orbital resonance which leads to significant
precession of their orbits. The causes the transits to be somewhat
unpredictable and by observing the transits we can learn more about the
orbital dynamics of the system.


 The purpose of the campaign is to detect transits of planet "b" if they
are occuring, or to convincingly rule them out. Below are the 
transit windows:


=== Observations


Transit Prediction:
         October 21 23:22 UT - October 22 03:27 UT 
w/3 sigma uncertainty:
         October 20 11:22 UT - October 23 15:27 UT


 ** Observations are needed during the entire 3 sigma window!! **


 In addition, IL Aqr is a variable star that has not been well monitored.
It has a tiny GCVS range of V=10.15-10.19, however that is just 
enough to interfere with transit detection. We need observations of IL Aqr 
to begin now so we can set a baseline of activity. Please begin observing 
IL Aqr at least once per night in B and V with as high precision as possible. 
Use the 119 comp star on the chart (below) and set your exposure for a good
SNR. If possible, get a few time series runs in of at least four hours. 
Submit your data as soon as you can so we can evaluate IL Aqr's typical 
activity (so as not to confuse it with any transit activity). 


 An e-scale chart has been created with 3 comparison stars from ASAS-3.
It can be downloaded at:
     http://www.aavso.org/cgi-bin/searchcharts3.pl?name=il%20aqr
[obsolete link; create charts using VSP at http://www.aavso.org/vsp ]

 The predicted transit depth *could* be relatively large, up to 0.1  
magnitude. However detection of a transit is not assured, much less 
its amplitude! 


 However, there is a catch. IL Aqr is a very red star so you need 
to use a filter, preferably a V filter. Also, be sure to use the 
star labelled 119 on the chart as your comp star and use the others 
as check stars. The 119 star is also red, but not as much, so it 
will provide more accurate photometry for untransformed observations.


 Observers should begin practicing on the object right now to make sure
you can achieve the required level of precision. Try to get 0.01 mag
precision to look for structure in the transit light curve. Time 
resolution is not as important as photometric precision.


=== Sign Up!


 Please observe as much as possible during the 3 days. We are creating 
a list on our web site of observers who can participate and during what 
windows they can observe. Please sign up by e-mailing aaronp@aavso.org 
with:


 Name, observer code, location, time zone and when you can observe. 


 This will help us coordinate observations between observers. 
Weather has been a real challenge with prior observations of this 
object so we need multiple people observing from multiple locations 
around the globe. 


=== Coordination


 A web page will be setup and maintained during the campaign:


          http://www.aavso.org/news/ilaqr.shtml
[ obsolete link; page is at http://www.aavso.org/ilaqr ]

 The campaign will be coordinated via the web page and the AAVSO-
Photometry Discussion Group. Visit the web page for links to the
discussion group archives, updated light curves, progress reports, links
to charts and more information. If you plan to participate in the
campaign send us a note and we'll put you on the web page.


 During the campaign itself we may setup a chat server for observers to 
participate in.


 This transit would be of GJ 876b, the first (outer) planet discovered in
the system. Details on the system and other transit results can be found
at http://www.ucolick.org/~elaugh/GJ876____c.results.html


 The results of this transit will be combined with other transit results
and research and submitted for publication. All observers who contribute
significant photometry to this effort are welcome to be listed as
co-authors of the manuscript.


 Note: IL Aqr was also the subject of Alert Notice 281 issued on May 11, 
2001 and CCD Views Vol. 2 No. 1 for June, 2001. It can be read at this URL:
http://www.aavso.org/publications/ccdviews/ccdviewsvol2no1.shtml [obsolete link; read at http://www.aavso.org/ccd-views-june-2001 ]
 
 If you have any unsubmitted data from those publications please submit 
them as soon as possible. They may be very valuable!

1. INTRODUCTION
 
 The AAVSO-Photometry Discussion Group has really come into its own the
last two months. In July it was a great tool for coordination of the Var
Her 04 campaign and posting of preliminary results and daily updates. In
August it has been a great place for discussion of photometric issues
ranging from error reporting to transformation coefficients.
 
Please consider joining the AAVSO-photometry Discussion Group. If
you are worried about being deluged with e-mails then choose the Daily
Digest version, which sends you one e-mail per day with all the posts
included in it. Or you can avoid subscribing and just read the discussion
group via our online archives. Just remember to come back every few days
to stay up on the latest and greatest in variable star photometry.

Our intensive campaign in June and July has been most interesting and rewarding. Those who did not follow the action on the photometry discussion group can go here for a link to the archives and the raw data: [link removed]
 
At the AAVSO Spring Meeting in Berkely I gave a short talk on both BZ UMa and Var Her 04 detailing our observing strategies and a quick look at analysis of the results. It is available online at: [link removed]
 
 We received a little over 7,500 CCD measurements of Var Her 04 from 23 observers over 16 days. The light curve is characterized by a steady decline of 0.017 magnitudes per day until June 24.5 . An inflection in the light curve gives rise to a gentle hump that spans 0.1 magnitudes over 2 days. Then the light curve resumes a slow decline until June 30.053 when a rapid decline began. The decline was terminated after 0.5062 days and a drop in ~1.1 magnitudes. The star remained steady at ~V=16 through the end of observations on July 16.237.
 *Very* preliminary analysis at this point is supporting the UGSU type. However, there are some questions that need to be answered before we are sure. There are also lots of complicating factors such as a companion ~1 arc second away which may be variable in itself. It is still possible that this is a unique class of CV and could end up being one of the oldest CV systems detected. We are investigating all these possibilities.
 A brief report of your observations was issued as IAUC #8734. We have assembled a team to work on a paper for this object. We hope to have something prepared and submitted by October, which of course means it will likely be after that! Those who contributed significant observations will be listed as co-authors and were e-mailed more details last week.
 We will continue making public updates via CCD Views and the Discussion Group.
 
--------------------------------------------------------------------------
 
3. BZ UMA UPDATE
 
We haven't forgotten our friend in the belly of the great bear. BZ UMa has proven to be very difficult beast to tame. Our data is noisy because it was faint and, lets face it, for many of us this was our first attempt at high speed, faint photometry. Careful analysis of the data reveals the orbital period and a 0.033d period that comes and goes in the light curve, but is not consistent (a wavelet plot of this can be seen in the PowerPoint presentation listed in the previous article). Other than that, the light curve is dominated by heavy flickering and the power spectrum dominated by its associated red noise. What we really need is X-Ray observations to determine the spin period. There are a number of opportunities for just that in the coming months and we are pursuing them. We'll keep you updated via CCD Views and the coauthors via e-mail updates.
 
--------------------------------------------------------------------------
 
4. BRIGHT STAR PHOTOMETRY
 
[Thanks to Arne Henden for much of the advice below.]
 
A good discussion of short exposure photometry occured on the AAVSO_Photometry Discussion Group in July. It can be read via the archives here: http://www.aavso.org/pipermail/aavso-photometry/2004-July/subject.html
 
As previously announced, the AAVSO is in the process of creating a program to detect exoplanet transits. The project will involve the monitoring of many bright stars with known planets but of unknown inclination (thus we're not sure if they transit or not). With all this emphasis on faint objects recently we wanted to summarize the results of this discussion of bright objects.
 
There are two main problems with high-precision short-exposure photometry (SEP from here on out). First, bright sources tend to get overexposed, especially if any nearby comparison star is fainter than the target. Antiblooming gate (ABG) CCDs typically saturate at about 50% of their full well depth, and many non-ABG chips saturate before the limit of their Analog/Digital Converters (ADCs). Second, the atmosphere itself conspires to degrade the photometry through a phenomenon called scintillation, where the turbulent bubbles of gas act like lenses, increasing or decreasing the amount of flux entering the front of your telescope. The twinkling of naked eye stars is caused by scintillation.
 
To counteract saturation, first test your CCD camera to find out the limits of its linearity and where full well occurs in the dynamic range of your ADC. Then keep the signal level within the linear range and below the full well. For very bright sources, you may reach a limit where you cannot take a short enough exposure to prevent saturation. Techniques to go even brighter include:
1. Stopping down the aperture of your telescope by using a mask with a cutout hole. You can often place the cutout so that the incoming light avoids the central obstruction and spiders.
2. Using a photometric filter, especially a blue one. The filter decreases the bandwidth and therefore decreases the amount of light reaching the CCD, enabling longer exposures. Using a blue filter further moves the incoming light to a wavelength regime where the CCD is less sensitive, enabling longer exposures.
3. Defocussing. While you don't want images with "donuts", you can often increase the image profile by a factor of two or more, thereby decreasing the central peak intensity.
4. Using a Barlow lens. Increasing the image scale spreads the starlight over more pixels, decreasing the peak intensity.
5. Wait for a night of poor seeing!
6. Often a night with uniform cirrus can be used, since such clouds decrease the incoming flux.
 
Scintillation can be tricky. It is stronger nearer the horizon where you are looking through more atmosphere. It is also stronger for smaller telescope apertures, where each blob of atmospheric gas is closer to the telescope aperture size (bigger telescopes average many blobs). It is also a function of wavelength (redder is better) and exposure time (longer is better). Tips to avoid scintillation:
1. Use relatively long exposures (10 seconds or longer). Use the techniques listed above to increase exposure time if necessary.
2. Don't work close to the horizon. We usually recommend staying above airmass 2.5 if possible.
3. Take multiple exposures and average to beat down the effects of scintillation.
 
Here is a formula posted By Radu Corlan (CXR) for estimating scintillation without taking altitude into consideration:
scint = (0.09 * A ^ 1.75) / (D ^ 0.66 * sqrt(2 * t))
Where A is the airmass, D is the aperture in cm and t is the integration time in seconds.
It is taken from a series of papers by Dravins et al. that begin with "Atmospheric Intensity Scintillation of Stars, I. Statistical Distributions and Temporal Properties" 1997, PASP. 109, 173.

5. SWIFT STATUS & GRB AFTERGLOW ACTIVITY REPORT
 
There has not been much activity in the past four months. However, SWIFT is scheduled to be launched in early October. Good localizations are expected in mid November with their quality gradually increasing afterward. SWIFT is planning to follow an afterglow for at least 5.5 hours after detection.
 
SWIFT is expected to detect one GRB about every other day. Of these, we expect one GRB afterglow should be viewable from each observer's location every other week after accounting for daylight, weather and lunar interference. That is a lot of work! Remember, the race will no longer be about identifying and localizing a GRB from SWIFT. It will be about building high quality lightcurves. If each member of the High Energy Network observes one afterglow per month we would quickly build a substantial database of afterglow light curves which could be very popular among the researchers.
 
It is important to note that amateur observations of GRBs are still needed! In fact, NASA recognizes that and has given the AAVSO a nearly $50,000 grant to continue and expand operations of the High Energy Network in direct support of the SWIFT mission. Amateurs will be needed to build light curves after SWIFT stops monitoring the burst. In addition, the SWIFT monitoring telescope (UVOT) is a near UV-optical hybrid. It has a detector with a response range of 170-650nm. It peaks in the Johnson B band, has a little V sensitivity and no R or Ic coverage. Ground based observations in VRI will still be needed to complement the near-UV observations of SWIFT. In fact, SWIFT is planning to distribute the first UVOT image of the field for use as a finder chart for observers on the ground. The SWIFT team recognizes that they are part of a collaborative effort with ground based astronomers.
 
More information, including the SWIFT observing policy in Word and PDF format, can be found at this URL:
 
Below is a listing of the AAVSO International High Energy Network GRB observation reports since the last issue of CCD Views:
GRB040717: Zsolt Kereszty (KZX) imaged the field and did not detect anything down to R=17.95. To date, no optical transient has been reported by anyone else via GCN.
GRB040730: Berto Monard (MLF) imaged the field and did not detect anything down to CR=19.5 . To date, no optical transient has been reported by anyone else via GCN.
GRB040810: Berto Monard (MLF) imaged the center 22x20 arc minutes of the field and did not detect anything down to CR=17.5 under deteriorating weather conditions. To date, no optical transient has been reported by anyone else via GCN.

8. ONLINE LIST OF AAVSO CCD CHARTS
 
Tim Crawford (CTX) recently assembled a list of AAVSO charts that have extended photometric information for CCD observers. Most of these charts have the data listed in a chart table in the lower righthand corner of the charts. The listing here includes the star designation, name, type, period, range and the filters for which photometric data is available (UBRI). AAVSO HQ is now maintaining this list on a web page and will update it when a new chart is issued with extended photometric information.
 
This is a good place to go when looking for new objects to add to your program. Currently we only add CCD tables to charts when there is a specific need for CCD observations of the object.
 
All charts can be found at http://www.aavso.org/vsp.

1. INTRODUCTION
In the last few months our CCD program has been very active. Campaigns have been run on CVs, blazars and exoplanet transit objects. In fact, we've had so many campaigns that we created a web page to keep track of it all: http://www.aavso.org/observing-campaigns . The page includes a timeline of all our active campaigns along with those in the recent past and upcoming campaigns. When planning the next few days of observation we recommend stopping by that page for new projects.

We opened the AAVSO Chat Room during the BZ UMa campaign to test its usefulness as a coordination mechanism. It seemed to be very popular with people logged in almost all the time during the entire week of the outburst. While the chat room is open to the public every Thursday, we plan to open it for longer periods during future campaigns.

The AAVSO Photometry Discussion Group has also been active with discussion about other types of campaigns and how often we should run them. The response I gathered from the discussion was: Bring it on! It seemed that the only limiting factor in observing activity is weather. So be careful what you ask for, you just may get it. :) Stay tuned for a very exciting and eventful 2005! And it doesn't hurt that we now have one of the world's best photometrists ON STAFF! (see below)
Clear skies,
Aaron

2. ADDRESS FROM THE NEW AAVSO DIRECTOR, DR. ARNE HENDEN
Obviously, I come from a technical background and welcome the rapid increase in quality of both telescopes and CCD cameras in the commercial world. The US$1000 barrier for CCD cameras has been broken by several vendors, CMOS cameras are just around the bend, and I forsee the day when cameras are given away like eyepieces with every telescope purchase. We see amateurs obtaining millimag precision; others imaging GRB afterglows at 21st magnitude. I think one of the roles of the AAVSO will be to provide instruction, through tutorials and workshops, so that amateurs and professionals alike can learn how to obtain scientifically usable data.

We will always have visual observers in the AAVSO - they are the life and blood of the organization. The century-long timeseries on Miras and other variables, the dense coverage on CV outbursts, are all suited to visual studies. CCD observers expand on this base and attack other problems - very low amplitude variables, targets where color information is important, high time resolution, etc. Our goal in the AAVSO should be to support all observers, no matter what technique they use to obtain their data, in such a way as to get the highest possible precision and maximal scientific content.

CCD observing is still in its amateur infancy. We will be running more pro-am campaigns to show both professionals and amateurs what can be done with this photometric technique, and will pursue new directions such as whole-earth 24-hour campaigns, exoplanet transits, quiescent studies of cataclysmic variables and ground-based support for high-energy space missions. It is going to be a fun future!

- Dr. Arne Henden

---------------------------------------------------------------------------
3. VV PUP CAMPAIGN IN SUPPORT OF KECK OBSERVATIONS
Dr. Steve Howell, WIYN Observatory & NOAO, has requested observations of the polar VV Pup to coincide with observations being done at the Keck Observatory on February 16, 2005 (UT). Time series observations for as long as possible in BVRI are requested from 00:00 UT February 15 - 23:00 UT February 17, 2005. VV Pup is quite faint and also near the quarter Moon during the observing window. So we recommend the following observing plan:

1) Observe it in one filter instead of alternating between filters. Set your exposure time to get an SNR > 20. You may need to stack images to reach this SNR.

2) Small and moderately sized telescopes should observe in Ic first and in Rc if you don't have an Ic filter or someone else is currently observing in Ic. This will lessen some of the effects of the Moon and also lower exposure time (this is a field with heavy extinction). Those with larger apertures should go for V and B photometry.

3) Post to the aavso-photometry discussion group and tell us what filter you are using and the expected start and end time of your observation run. This way someone else can use a different filter if they are observing at the same time.

We currently have very few observations of VV Pup. So baseline observations prior to and immediately after the observing campaign would be very useful.

The AAVSO Chat Room will be open for this event! Join us during the campaign at http://www.aavso.org/chat .

The VV Pup chart is here: [link removed - please use our Variable Star Plotter to create an updated chart]

Our observations of VV Pup are minuscule!! We desperately need some photometry. Our latest observations of VV Pup:
VV PUP JAN 01.4960 <15.3 SRX Visual
VV PUP DEC 31.8280 17.2 CCD MLF Unfiltered
VV PUP DEC 28.4424 16.305 CCDI CTX ERR: .03
VV PUP DEC 23.4785 18.38 CCDV CTX ERR: .027

CTX - Tim Crawford, Oregon, USA

---------------------------------------------------------------------------
4. CCD TIMING RECOMMENDATIONS & PITFALLS
There are two main sources of error when it comes to CCD image timing. The first source is the accuracy of your computer clock. We recommend that you sync your clock with either WWV via a short wave radio or use one of the US Naval Observatory's NTP Internet servers:
tick.usno.navy.mil
tock.usno.navy.mil
Many deluxe GPS systems can now be purchased with an interface to your computer which will update your system clock with the GPS signal.

Regardless of the system you use, please update your clock before *each* observing run.

Another source of error is in unknown recording of the time into the FITS header by your camera control software, especially when stacking images. It has been reported that some software records the time of the first image, the last image, an average of the images, etc. What should be reported to the AAVSO is the midpoint of the observation.

At the URL below I have put online 4 FITS images. [Link removed] Please download the four images and stack them in your software. Post to the AAVSO Photometry Discussion Group (or e-mail me if not subscribed) the time that your software recorded in the final image.
Send us:
1. Software Name
2. Software Version (usually found in the "About" menu)
3. Time listed in the FITS header of the stacked image.

In the next issue of CCD Views I'll post a list of the various software packages and how they handle the timing of stacked images. We will use that to recommend ways to compensate for the peculiarities of various photometry packages.

---------------------------------------------------------------------------
5. THE RECENT BZ UMA OUTBURST CAMPAIGN
BZ UMa went into outburst again on January 16, 2005. The AAVSO commenced a high intensity observing campaign for the duration of this short outburst (~5 days). AAVSO observers did a fantastic job building a solid light curve with complete coverage for almost 24 hours when the outburst peaked. The light curve, data and notes on the outburst can be found here: [link removed]

This outburst follows on a campaign the AAVSO conducted on a BZ UMa outburst in February, 2004 which resulted in an IBVS publication. A subsequent quiescence campaign was conducted in April with inconclusive results. We hope the addition of this new, large and high quality data set will help shed light on this enigmatic system, which is yet to be classified. We will be working with the data in the coming weeks and will post updates to the aavso-photometry discussion group. So far superhumps are still missing but some interesting features in the decline may give us a few clues.

---------------------------------------------------------------------------
6. HIGH PRECISION PHOTOMETRY WORKSHOP AT AAVSO SPRING MEETING
Arne will be holding a high precision photometry workshop at the upcoming 3rd High Energy Astrophysics Workshop for Amateur Astronomers being held alongside the AAVSO 94th Spring Meeting. The goal of this workshop is to follow up on previous workshops at AAVSO meetings with a more advanced program focusing on high precision photometry of faint objects. The additional training is important as we expand into fainter categories of stars (blazars, quiescent CV photometry) and stars that need ultra high precision photometry (exoplanet transits).

Also, during the AAVSO paper session an introduction to IRAF will be presented which we hope will lay the groundwork for an IRAF workshop at the AAVSO Annual Meeting in October. A limited number of travel grants are available for meeting attendees. Visit the following URL to apply: [link removed]

P/S: Arne and Brian Warner will be giving a workshop about using Canopus software for photometry on May 24, 2005 in Big Bear, CA. This workshop is not affiliated at all with the AAVSO but many AAVSO observers do use Canopus. For more info visit: [link removed]

---------------------------------------------------------------------------
7. INFRARED FILTER GRANTS AVAILABLE
The AAVSO has received a generous grant from the Curry Foundation to purchase CCD filters for use by members of the AAVSO International High Energy Network. We have 15 Iz (SDSS z') and 10 Ic filters available for semi-permanent loan.

The Iz filters are intended for use in GRB afterglow hunting. The Ic filters are intended for use in monitoring blazars for the High Energy Network but can also be used for other variable star projects. If you would like to receive one of these filters please fill out the application at the URL below. [link removed]

---------------------------------------------------------------------------
8. NEW SCINTILLATION & AIRMASS CALCULATORS ONLINE
We have put online a tool to automatically do airmass and scintillation calculations for you. It can be accessed at this URL: [link removed]
The results page will give you the airmass of an object and (optionally) the scintillation. The computation is a rough approximation but should be good enough for most photometry calculations. A table of projected airmass and scintillation for the next ten hours is also displayed. The algorithms used for both approximations are referenced at the bottom of the results page.

1. INTRODUCTION

The 3rd High Energy Astrophysics Workshop for Amateur Astronomers was a great success. Word on the grapevine is that this was one of the best AAVSO meetings in recent memory. We at HQ were particularly glad to be able to meet many new AAVSO observers and put faces to the observer codes. That is always my favorite part of the meeting. Well, that and the fact that new observers often say to me "You look much younger than I envisioned!" A little flattery will get you everywhere.

The PowerPoint presentations from the workshop will be available on our web site within a week or so. In addition, full video in glorious Quick Time .AVI format will be online in 1-2 months. There were many great talks about High Energy Network objects such as GRBs, blazars and polars. Also, Arne's Advanced CCD Photometry Workshop will be available in video. While they all will be available online, attendees will also receive DVDs of the talks and workshops.

Why is this worthy enough to take up the valuable real estate of the CCD Views "Introduction"? Because it means more work for you! The meeting was such a success that we are getting lots of questions about how to start observing all of these objects. In this issue of CCD Views we give some starting points on observing blazars and polars along with a recent history of GRB afterglow reports from network members. We also have campaigns lined up for miras, eclipsing binaries and more exoplanet work.

So lots to do in the coming months, get ready!

2. VAR HER 04 QUIESCENT PHOTOMETRY CAMPAIGN

The seasons have changed and now Hercules is among us again. This means it is time to revisit our old friend Var Her 04. Dr. Jana Pittichova is helping us observe Var Her 04 with the University of Hawaii 2.2m on Mauna Kea this Sunday, April 17. She will observe in B to filter out light from the faint red companion 1 arc second way.

From you we need time series observations of Var Her 04 mainly in V throughout the entire day of April 17. We also need baseline observations of Var Her 04 in V beginning now and lasting until May 1.

We also need one or two observers to observe in Ic on April 17th. If anyone has an Ic filter and can observe please e-mail aaronp@aavso.org and/or post to the AAVSO Photometry Discussion Group.

Precision is very important for this faint system. Set your exposures for an SNR of 100.

As always, we will coordinate this campaign and post updates through the AAVSO Photometry Discussion Group.

Latest Var Her 04 observations:

3. INFRARED CCD FILTER GRANTS - LAST CALL FOR APPLICATIONS

We still have a few 1.25" Ic and Iz CCD filters available from the grant program announced in CCD Views #330.

The Iz filters are intended for use in GRB afterglow hunting. The Ic filters are intended for use in monitoring blazars for the High Energy Network but can also be used for other variable star projects. If you would like to receive one of these filters please fill out the application at the URL below. Priority will go to those who attended Arne's CCD Photometry Workshop at the HEA3 meeting. [Link Removed] These filters were funded by a grant from the Curry Foundation.

4. GRB OBSERVATIONS (AND APRIL FOOLS DAY ALLEGORY)

>> Positive GRB Afterglow Observation(s):

* Congrats to Stefano Sposetti of Switzerland who successfully imaged the afterglow to GRB050319. He took 83 60-second frames to get down to a LM of 21.5 unfiltered! That is no typo, folks. 83! The afterglow magnitude was 20.5 +/-0.5 mag unfiltered. WAY TO GO, STEFANO! But remember, next time we need filtered photometry. :)

>> Fainter Than/Negative Observation(s):

* GRB050412: Peter Nelson observed the region and did not find an afterglow. Two professional observatories reported possible faint (V>21) afterglows.

* GRB050410: Arto Oksanen observed the region and did not find an afterglow. SWIFT detected an X-ray counterpart but no optical afterglows were detected by anyone.

* GRB050408: Andrea Tasselli, Dr. D. T. Durig (Cordell-Lorenz Observatory) and Bill Dillon observed the region and did not find an afterglow. Professional observatories did discover an afterglow and even got a red shift of z=1.236 for it (8.6 billion light years away).

* GRB050331 (April Fools GRB): This was announced by SWIFT on March 31. Shortly after the announcement SWIFT also reported a bright (V>13!) afterglow that saturated the UVOT. Berto Monard was on the GRB and imaged the field and reported *no* afterglow. We were nervous contradicting the SWIFT UVOT but issued a GCN anyway. A few minutes later SWIFT retracted the GRB detection and Berto's negative observation was confirmed. This was a nice example of everyone working together and why sometimes a human at the telescope is still more valuable than an automated system!

* GRB050326: Berto Monard observed the field under poor observing conditions (wind and lunar interference). An afterglow was not detected down to 18.0 unfiltered magnitude 16.5 magnitude. However, a new source of some type (new variable star?) may have been discovered in the field. XMM Newton discovered an X-Ray afterglow.

* GRB050313: Durig and Kereszty Zsolt both imaged the field. Neither detected an afterglow and neither did any other professional observatory. In hindsight this may not have been a real GRB detection.

Nice job getting on the fields and submitting your reports!

          Neil deGrasse Tyson is creating a ‘Space Odyssey’ video game that's scientifically accurate        

Neil Tyson Space Odyssey

Astrophysicist Neil deGrasse Tyson is making a video game about space exploration.

Or trying to, anyway — the Kickstarter for the project went live on June 13 and runs through July 29. At the time of writing, they've raised $43,240 of the $314,159 goal (get it?).

The game, called "Space Odyssey," would "allow players to travel through the cosmos to scientifically accurate planets, moons and exoplanets based in real science," according to a press release emailed to Business Insider. Tyson and co-creators' basic concept seems to be a captivating interactive experience that still follows scientific principles.

"I have no patience for people who say, 'I don't want the laws of physics to constrain me,'" Tyson said while discussing the game at the video game E3 convention in Los Angeles this week.

"Space Odyssey"

On the Kickstarter page, the team behind the game promises a long list of potential activities: "Develop planets, colonize worlds, nurture species, mine elements, build robots, and discover unique life-forms as you coordinate with others in an intense game of real-time strategy."

Space Odyssey

Players would supposedly begin by exploring Proxima B, the closest known exoplanet to our own solar system, just over 4 light years away (there are real-life plans to try to send mini-spacecraft there). After exploring the surface of that planet and learning how the science-based physics systems work (with Tyson as your guide), players would be ready to start the main event. Beginning at a space station, they'd create and terraform a home planet and system, taking into account real aspects of biology and chemistry. That system can include be colonies and outposts — and you can play solo or with friends.

Players would also need to protect their systems from threats, including environmental disaster, space objects, climate change, disease, and the changes brought about by evolution and whatever else may happen to a planet.

Luckily, a digital assistant with Tyson's soothing voice would guide you through all of this.

Players would also be able to design a spacecraft to explore galaxies created by friends or "prominent scientists and fictional world-builders like Tyson, Bill Nye, George R.R. Martin, Neil Gaiman, and Peter Beagle," according to the Kickstarter.

Space Odyssey

Plus, there would be bonus virtual reality (VR) missions.

The company behind the game is called Space Media Ventures. The team includes producers who have worked in games, movies, and VR; the comics creator behind "Wolverine"; and artists who have worked on games like "God of War 3."

Tyson's role seems to be largely inspiration and helping ensure that the game stays true to real science.

Mark Murphy, partner and creative director at Space Media Ventures, tells Business Insider that Tyson "is always teaching and supporting creative thinking. He has exciting ideas for exploration, challenges and missions. He is a terrific collaborator and an immense scientific resource. He and his team of Star Talk All-Stars place us at a tremendous advantage in creating exciting and engaging gameplay."

An ambitious undertaking

"Space Odyssey" seems to involve building activity similar to "Minecraft," space colonization akin to that in  "Civilization: Beyond Earth," elements of exploration like "No Man's Sky," and echoes of Elon Musk's favorite rocket-building simulator, "Kerbal Space Program." Plus a whole lot of real (and really cool) science.

That's ambitious, especially since the anticipated launch date of "Space Odyssey" is January 2019.

Space Odyssey

With all that to design, the Kickstarter funding seems unlikely to be sufficient for the project. But a secondary purpose of the Kickstarter may be to encourage community members to interact with and and influence the game.

"[W]e do have other funding sources for the game; those sources are not contingent on the crowdfund. For us this is a committed community build, we want the people who will be playing our game to have the opportunity to engage while the build is underway," Murphy told Business Insider. "We are committed to providing an enhanced physics experience which we call experiential physics that will elevate game play regarding modding, mapping and building and expressed action. I think it's fair to say our budget exceeds our community raise goal."

It's hard to say whether everything will really come together by January 2019, but whenever the game gets released, we're excited to play — and learn while doing so.

          Ø£ÙƒØ¨Ø± 8 أشياء في الكون        

- عندما تقف بجانب أهرامات الجيزة لا يسعك إلا أن تتعجب , وكذلك الحال إذا نظرت من فوق برج دبي في الإمارات العربية , لتجد نفسك أمام السحاب ... فتتصور أنك أمام أكبر الأشياء في الكون .. ولكن في الحقيقة في الكون ما هو أكبر من ذلك بكثير , فهناك أشياء في الكون ستبدو لها أضخم الأشياء على الأرض وكأنها صوراً مجهرية ... فتعالوا لتتعرفوا على أكبر 10 أشياء في الكون الذي نعرفه :


1- أكبر كويكب 


- سيريس Ceres هو أكبر الكويكبات التي تم إكتشافها حتى الآن , إذ يحتوي على 1/3 كتلة حزام الكويكبات بأكمله , وتقريباً يصل إلى 600 ميل في القطر , أي أنه في حجم ولاية كاليفورنيا , ولديه جاذبية هائلة جعلته يتخذ الشكل الكروي , فهذا الكويكب كبير بما يكفي ليأخذ لقب ( كوكب قزم ) , فهو الكائن الوحيد في حزام الكويكبات الذي يستحق هذا اللقب وعن جدارة .


2- أكبر كوكب


- يقع أكبر كوكب في كوكبة هرقل وهو TRES4 , اكبر بنسبة 70% من كوكب المشترى في القطر , ويحتوي على 80% من كتلة المشترى , وبسبب قرب هذا الكوكب من النجم الذي يدور حوله , فإن الحرارة الشديدة تعمل على تمدد الغازات التي شكلت هذا الكوكب , مما أدى إلى جعل كثافته تشبه كثافة ( حلوى الخطمى ) .



3- أكبر نجم


- يو واي سكوتي UY Scuti هو أكبر نجم معروف حتى الآن , لديه متوسط نصف قطر يقدر ب 1708 نصف قطر الشمس , أي أن حجمه 5 مليارات مرة من الشمس. ويبعد حوالي (9500 سنة ضوئية) من الأرض. إذا وضعناه في مركز النظام الشمسي، فإن غلافه الضوئي سوف يبتلع مدار كوكب المشتري . 


4- أكبر ثقب أسود 


- إكتشف الباحثون من جامعة تكساس , بإستخدام تلسكوب هوبي ايبرلي Hobby-Eberly أكبر ثقب أسود هائل حتى الآن , بحيث تصل كتلته إلى حوالي 17 مليار كتلة شمسية , ويقع في مركز مجرة NGC 1277 , ويمثل حوالي 14% من كتلة المجرة بأكملها .


5- أكبر مجرة 


- أى سى 1101 - IC 1101  Ù‡ÙŠ أكبر مجرة مكتشفة حتى الآن , وهي مجرة إهليجية عملاقة تقع في كوكبة العذراء , وإكتسبت حجمها الهائل من خلال إصصدامها بعدد من المجرات الأصغر حجماً , ويبلغ قطرها حوالي 6 ملايين سنة ضوئية , بالمقارنة مع قطر مجرة درب التبانة التي تبلغ فقط 100,000 سنة ضوئية , وتحتوي تلك المجرة العملاقة على 100 تريليون نجم , ومعظم كتلة المجرة تتكون من المادة المظلمة .


6- أكبر باعث ليمان ألفا


- Lyman-alpha emitter هو  Ù†ÙˆØ¹ من المجرات القديمة و البعيدة و الإسم لايمان نسبة لمكتشف خطوط الطيف لذرة الهيدروجين الفيزيائي الأمريكي ثيودور لايمان عام 1906. و هى سلسلة من خطوط الطيف او الخط الطيفي لذرة الهيدروجين والذرات المشابهة لها  . و باعث ليمان ألفا نوع من المجرات البعيدة التي تنفث إشعاع ليمان ألفا ، مجرات انبعاثات ليمان ألفا بعيدة للغاية ، و بسبب الوقت الذي يستغرقه السفر المحدود للضوء فإنها توفر لمحات من تاريخ الكون , وأكبر واحدة تم رصدها يصل قطرها إلى 200 مليون سنة ضوئية , وتقع في كوكبة الدلو .


7- أكبر منطقة فراغ في الكون 


- تتواجد المجرات عادة في مجموعات , حتى مجرتنا درب التبانة , ولكن هناك أيضاً فراغ يحيط بالجرات وبمجموعات المجرات , وهو يمثل الهيكل العام لبنية الكون , فالمجرات تتجمع فيما يشبه النسيج وموزعة حول فراغات هائلة .
وقد إكتشف العلماء أكبر هيكل فراغي حتى الآن يصل قياس قطره إلى 1,8 مليار سنة ضوئية .


8- أكبر عناقيد المجرات 


- مجموعات المجرات هي تجمعات للمجرات تتكون من حوالي 50 مجرة , وعنقود مجري هايل شابلي , يشكل أحد أكبر تجمعات عناقيد المجرات لتي نعرفها ويبعد عنا نحو 700 مليون سنة ضوئية , ويضم مجموعة مجرات تقدر قطرها بأكثر من 400 مليون سنة ضوئية , لدرجة أن أسرع مركبة فضائية لدينا ستستغرق تريليونات السنوات في محاولة عبوره .

          EL SER INTEGRAL - PDF (CÓMO LLEGAR AL SUPER HOMBRE)        
Andrea Victoria Cano/Autor
Saludos a todos los seguidores del blog de Sabiduría Exoplanetaria, soy Andrea Victoria Cano y me es grato llegar a todos ustedes con novedades en este 2017, el nuevo libro de mi autoria: EL SER INTEGRAL. 

El Ser Integral fue mi primer proyecto literario que vislumbre en el año de 1998, en la confusión total en la que me encontraba lo logre publicar en el año 2002, aunque sentía la intuición de que era necesario llegar a una integralización y que no solo estamos compuestos de cuerpo, mente y alma, sino de un espiritu, no era esencialmente trascendente ni evocaba una finalidad ni tampoco una funcionalidad. 

Ya que lamentablemente la mayoría de las personas confundimos el alma y sus características anímistas, con lo increado del espiritu que se encuentra fuera de este mundo material, sin dejar atrás por supuesto la desorientación producto del sistema globalizado, que influye en todos nosotros evitando así nuestra transcendencia, cosa realmente alarmante.

Pero no fue hasta que llegue a la Sabiduría Hiperbórea de Nimrod de Rosario y al libro del Misterio de Belicena Villca del mismo autor , que se esclareció mi panorama, pudiendo entender a profundidad  lo que significa estar integrado y la preponderancia de lo espiritual en la complexión humana, sin obviar por supuesto las 18 obras restantes de autores hiperbóreos y científicos que complementaron mi investigación, haciendo que los conceptos lanzados en este libro sean precisos y reveladores.  

Esta nueva edición tratará una serie de temáticas muy censuradas, porque desmienten y desafían al sistema, veremos también que es lo que le  impide verdaderamente al individuo integrarse, por qué la apatía con su propio conocimiento fisiológico y espiritual, por qué la laxitud en la que se encuentra inmerso, por qué el desinterés por encontrar la verdad,  cuál es el motor metafísico que injiere para evitar esa integración, quienes y por cual razón o motivos impiden que lleguemos al Súper Hombre o Ser Integral, por qué hemos olvidado nuestro legado ancestral hiperbóreo, como alcanzar dicha integración, entre otras.

El Ser Integral complementa de una manera analítica, profunda y sin tapujos de ninguna índole, en que consiste la complexión total entre lo físico, mental, metafísico, esotérico y espiritual, por los cuales el individuo puede transcender del cuerpo material en el que esta inserto, vislumbrando así la Posibilidad Pura, ejerciendo un aporte importante a nivel social e individual.  

La Virgen de Agartha es el símbolo de la Guerra Esencial contra las Potencias de la Materia y ella exige de todos sus veneradores Hielo en el Corazónpara no someternos nunca a las debilidades del alma: “MORIR CON HONOR LUCHANDO PARA SER LIBRES, ANTES QUE SEGUIR VIVIENDO COMO ESCLAVOS”.

          PROYECTO OVNIS 4 - LA BATALLA FINAL PDF        
Pablo Santa Cruz de la Vega - El Autor
Cuando comenzamos Proyecto Ovnis, hace 5 años, jamás imaginamos que se convertiría en un fenómeno cultural, no sólo en Bolivia, si no, a través del Internet, en todo el mundo. Evidentemente, además del éxito comercial, Proyecto Ovnis generó una cada vez más creciente audiencia para las temáticas esotéricas, pero esencialmente, para la gnosis hiperbórea y el interés por Belicena Villca, la última princesa inca. Proyecto Ovnis Radio tuvo la virtud de producir la primera radionovela esotérica en el planeta, y Proyecto Ovnis la Revista, el primer “Comic” esotérico e hiperbóreo. Entiéndase como “lo hiperbóreo” a todo el entramado argumental de naturaleza mítica, metafísica, protocultural, prehistórica e histórica, escondida, ocultada, distorsionada y censurada por la sinarquía mundial, nuevo orden mundial, aquel interés transnacional que busca concentrar todo el poder universal en sus manos.

Esta expansión de Proyecto Ovnis hacia la producción audiovisual, radiofónica y gráfica, trajo nueva y valiosa información que fue acumulándose, hasta el punto de llegar a constituirse en un referente importante para una segunda parte recargada, que sólo estaba esperando el kairos justo para emerger. Este Kairos se daría de manera impensada, y su protagonista sería una valiente revisionista colombiana, que después de una peripecia sin precedentes, se unió al equipo de Proyecto Ovnis atreviéndose a asumir el reto de realizar el tercer libro de la serie, embarcándose en un apasionante viaje por el esoterismo, la ufología y la sabiduría hiperbórea en un extraordinario ensayo, su primero de este tipo: Proyecto Ovnis El Origen.

En este cuarto libro de la serie, respaldamos con nueva información todas las revelaciones de los dos anteriores libros, ampliando aspectos relevantes en cuanto a los mundos intraterrenos, la base 211, así como dentro de la tipología de contacto y abducción. En cuanto a la gran revelación de la primera serie de Proyecto Ovnis referente al caso de contacto extraterrestre de Rosalía Taglialavore, el más importante de todos los tiempos por la difusión de la Sabiduría Hiperbórea de origen exoplanetario, acotamos ahora un caso de abducción y contacto parecido, que remarca la existencia de fuerzas alienígenas en la Antártida, así como la presencia de poderosos brazos de control supragubernamental que operan en el ocultamiento de esta información.

Astronomers have discovered four new exoplanets -- two of which might be habitable -- orbiting our nearest sun-like star just 12 light years away.
          Planeta habitável a 25.000 anos luz        


Graças ao método de lente gravitacional, que consiste em observar a curvatura da luz das estrelas (ou o conjunto delas), que passa a observar planetas que passam na frente delas cuja luminosidade fica mais fraca, astrônomos de Israel, Polônia, Japão e Nova Zelândia, detectado um exoplaneta em uma zona habitável, a cerca de 25.000 anos-luz.




Recordemos que uma "zona habitável" é aquela em que um planeta está dentro da distância necessária de sua estrela, sendo assim, a temperatura manteria a sua água no estado líquido, como acontece com a nossa Terra.




MOA -2011- BLG- 293Lb, como foi chamado o corpo celeste, se encontra no bojo galáctico da Via Láctea, orbitando um Sol 0,86 vezes maior que o nosso e possui uma massa cinco vezes maior que a de Júpiter. Ele é composto de gás e possui várias luas, lugar onde a vida poderia se desenvolver.




O planeta já tinha sido detectado em um par de anos atrás, mas não tinha sido comprovado até a análise posterior com os telescópios Keck , no Havaí, que identificou as características do corpo e do sistema solar em que ele esta inserido.

Scientists just got their first peek into the space between Saturn and its rings. And it's incredibly beautiful.

Last Wednesday, the NASA space probe Cassini made the first of twenty-two scheduled dives through the rings around the planet of Saturn.

No human-made object had ever reached so far into those whirling bands of ice and dust particles.

Cassini was traveling at a speed of 77,000 mph through regions that were thick with potentially destructive particles. It was made to using its dish-shaped antenna as a shield, to prevent any communication with Earth during the dive.

All day, scientists were anxiously awaiting confirmation that their courageous tiny space robot had made it through.

Not long before midnight Pacific time, the Deep Space Network (which is a group of telescopes which communicate with distant objects in space) managed to pick up Cassini's far-off signal.

As data began streaming a billion miles back to Earth, all people at ground control at the Jet Propulsion Laboratory in Pasadena, California, cheered massively. Cassini had made it through the gap and emerged on the safe side.

In September, the spacecraft's last dive will now be directed straight into Saturn itself, and the probe will be forever lost. But until Cassini's 'grand finale', we can be sure to anticipate some intriguingly beautiful images accompanied by some fascinating science.

The amazing pictures from Cassini's latest dive are being posted on NASA's website directly as they stream in. Here are some of them:

          Hubble Detects Exoplanet with Glowing Water Atmosphere        

Scorching "Hot Jupiter" Has a Stratospheric Layer

Only when we fly in a commercial jet at an altitude of about 33,000 feet do we enter Earth's stratosphere, a cloudless layer of our atmosphere that blocks ultraviolet light. Astronomers were fascinated to find evidence for a stratosphere on a planet orbiting another star. As on Earth, the planet's stratosphere is a layer where temperatures increase with higher altitudes, rather than decrease. However, the planet (WASP-121b) is anything but Earth-like. The Jupiter-sized planet is so close to its parent star that the top of the atmosphere is heated to a blazing 4,600 degrees Fahrenheit (2,500 degrees Celsius), hot enough to rain molten iron! This new Hubble Space Telescope observation allows astronomers to compare processes in exoplanet atmospheres with the same processes that happen under different sets of conditions in our own solar system.


          Icy Moons, Galaxy Clusters, and Distant Worlds Among Selected Targets for James Webb Space Telescope        

Webb Telescope Guaranteed Time Observations Targets Announced

Mission officials for NASA’s James Webb Space Telescope announced some of the science targets the telescope will observe following its launch and commissioning. These specific observations are part of a program of Guaranteed Time Observations (GTO), which provides dedicated time to the scientists that helped design and build the telescope’s four instruments. The broad spectrum of initial GTO observations will address all of the science areas Webb is designed to explore, from first light and the assembly of galaxies to the birth of stars and planets. Targets will range from the solar system’s outer planets (Jupiter, Saturn, Uranus, and Neptune) and icy Kuiper Belt to exoplanets to distant galaxies in the young universe.


          Hubble's Tale of Two Exoplanets: Nature vs. Nurture        

Atmospheres of Two Hot Jupiters: Cloudy and Clear

Astronomers once thought that the family of planets that orbit our sun were typical of what would eventually be found around other stars: a grouping of small rocky planets like Earth huddled close to their parent star, and an outer family of monstrous gaseous planets like Jupiter and Saturn.

But ever since the discovery of the first planet around another star (or exoplanet) the universe looks a bit more complicated — if not downright capricious. There is an entire class of exoplanets called "hot Jupiters." They formed like Jupiter did, in the frigid outer reaches of their planetary system, but then changed Zip code! They migrated inward to be so close to their star that temperatures are well over 1,000 degrees Fahrenheit.

Astronomers would like to understand the weather on these hot Jupiters and must tease out atmospheric conditions by analyzing how starlight filters through a planet's atmosphere. If the spectral fingerprint of water can be found, then astronomers conclude the planet must have relatively clear skies that lets them see deep into the atmosphere. If the spectrum doesn't have any such telltale fingerprints, then the planet is bland-looking with a high cloud deck.

Knowing the atmospheres on these distant worlds yields clues to how they formed and evolved around their parent star. In a unique experiment, astronomers aimed the Hubble Space Telescope at two "cousin" hot Jupiters that are similar in several respects. However, the researchers were surprised to learn that one planet is very cloudy, and the other has clear skies.


          NASA Telescope Reveals Largest Batch of Earth-Size, Habitable-Zone Planets Around Single Star        

NASA's Spitzer Space Telescope has revealed the first known system of seven Earth-size planets around a single star. Three of these planets are located in an area called the habitable zone, where liquid water is most likely to thrive on a rocky planet. The system sets a new record for the greatest number of habitable zone planets found outside our solar system. Any of these seven planets could have liquid water, the key to life as we know it. The exoplanet system is called TRAPPIST-1 and is only 40 light-years away. Following up on the Spitzer discovery, NASA's Hubble Space Telescope has initiated the screening of four of the planets, including the three inside the habitable zone. These observations aim at assessing the presence of puffy, hydrogen-dominated atmospheres, typical for gaseous worlds like Neptune, around these planets. In May 2016, the Hubble team observed the two innermost planets and found no evidence for such puffy atmospheres. This finding strengthened the case that the planets closest to the star are terrestrial in nature. Astronomers plan follow-up studies using NASA's upcoming James Webb Space Telescope, scheduled to launch in 2018. With much greater sensitivity, Webb will be able to detect the chemical fingerprints of water, methane, oxygen, ozone, and other components of a planet's atmosphere. Webb also will analyze planets' temperatures and surface pressures — key factors in assessing their habitability.

          NASA's Hubble Telescope Makes First Atmospheric Study of Earth-Sized Exoplanets        

The possibility of life on other worlds has fueled humankind's imagination for centuries. Over the past 20 years, the explosion of discoveries of planets orbiting other stars has sparked the search for worlds like Earth that could sustain life. Most of those candidates were found with other telescopes, including NASA's Kepler space observatory. NASA's Hubble Space Telescope has also made some unique contributions to the planet hunt. Astronomers used Hubble, for example, to make the first measurements of the atmospheric composition of extrasolar planets.

Now, astronomers have used Hubble to conduct the first search for atmospheres around temperate, Earth-sized planets beyond our solar system, uncovering clues that increase the chances of habitability on two exoplanets. They discovered that the exoplanets TRAPPIST-1b and TRAPPIST-1c, approximately 40 light-years away, are unlikely to have puffy, hydrogen-dominated atmospheres usually found on gaseous worlds. Those dense atmospheres act like a greenhouse, smothering any potential life. Observations from NASA's upcoming James Webb Space Telescope will help determine the full composition of these atmospheres and hunt for potential biosignatures, such as carbon dioxide and ozone, and methane.


          Cloudy Days on Exoplanets May Hide Atmospheric Water        

Water is a hot topic in the study of exoplanets, including "hot Jupiters," whose masses are similar to that of Jupiter, but lie much closer to their parent star than Jupiter is to the sun. They are estimated to be a scorching 2,000 degrees Fahrenheit, meaning any water they host would take the form of water vapor.

Astronomers have found many hot Jupiters with water in their atmospheres, but other hot Jupiters appear to have none. In a new study, scientists used exoplanet data from a single instrument on NASA's Hubble Space Telescope to uniformly characterize a group of 19 hot Jupiters previously studied with Hubble. They found that as much as half of the water in the atmospheres of the exoplanets may be blocked by these clouds or hazes. The new findings suggest that clouds or haze layers could be preventing a substantial amount of atmospheric water from being detected by space telescopes. The study is the first to quantify how much of the atmosphere would be shielded as a result of clouds or haze.

          Hubble Directly Measures Rotation of Cloudy 'Super-Jupiter'        

Though nearly 2,000 planets have been found around other stars, the light from only a handful of them has ever been collected by the world's most powerful telescopes. Ironically, a lot of them are detected by the shadows they cast, as they pass in front of their parent stars. Follow-up observations measure the planet's feeble, but telltale, gravitational tug on its parent star. Now, Hubble Space Telescope astronomers have been able to pick up the faint infrared glow of a giant planet located 170 light-years away from Earth. Not only is it glowing, but also rhythmically flickering as the planet spins on its axis like a top. The interpretation is that the subtle changes in the planet's brightness are due to a variegated cloud cover of comparatively bright and dark patches coming and going. These measurements have led to an estimate of how fast the planet is spinning through direct observation – a first for exoplanet astronomers. The gaseous world completes one rotation approximately every 10 hours, which, coincidentally, is the same rotation rate as Jupiter.

The planet is dubbed a "super-Jupiter" because it is four times the mass of Jupiter, the largest known planet in our solar system. Because the planet is a comparative newborn, it is still hot as it contracts under gravity. These characteristics allow for infrared observations. The planet orbits a faint brown dwarf, designated 2M1207. The dwarf is too small to shine as stars do through nuclear fusion. The dwarf is so dim and far from the planet astronomers were able to isolate the planet's glow.


          NASA Space Telescopes Solve Missing Water Mystery in Comprehensive Survey of Exoplanets        

A survey of Jupiter-sized exoplanets conducted with the Hubble and Spitzer space telescopes has solved a long-standing mystery – why some of these worlds seem to have less water than expected. Astronomers have found that planets called hot Jupiters (which orbit very close to their stars) that are apparently cloud-free show strong signs of water. However, atmospheres of other planets with faint water signals also contained clouds and haze – both of which are known to hide water from view. The findings show that planetary atmospheres are much more diverse than expected. Also, the results offer insights into the wide range of planetary atmospheres in our galaxy and how planets are assembled.


          Most Earth-Like Worlds Have Yet to Be Born, According to Theoretical Study        

Astronomers are conducting extensive observations to estimate how many planets in our Milky Way galaxy might be potential abodes for life. These are collectively called "Earth-like" – in other words, Earth-sized worlds that are at the right distances from their stars for moderate temperatures to nurture the origin of life. The search for extraterrestrial intelligent life in the universe (SETI) is based on the hypothesis that some fraction of worlds, where life originates, go on to evolve intelligent technological civilizations. Until we ever find such evidence, Earth is the only known abode of life in the universe. But the universe is not only vastly big, it has a vast future. There is so much leftover gas from galaxy evolution available that the universe will keep cooking up stars and planets for a very long time to come. In fact, most of the potentially habitable Earth-like planets have yet to be born. This theoretical conclusion is based on an assessment of star-birth data collected by the Hubble Space Telescope and exoplanet surveys made by the planet-hunting Kepler space observatory.


          Telescopes Team Up to Find Distant Uranus-Sized Planet Through Microlensing        

The majority of planets discovered outside our solar system orbit close to their parent stars because these planets are the easiest to find. But to fully understand how distant planetary systems are put together, astronomers must conduct a census of all the planets around a star. So they need to look farther away from the star-from about the distance of Jupiter is from our sun, and beyond.

Now, astronomers using NASA's Hubble Space Telescope and the W. M. Keck Observatory in Hawaii have confirmed the existence of a Uranus-sized exoplanet orbiting far from its central star, discovered through a technique called gravitational microlensing. Microlensing occurs when a foreground star magnifies the light of a background star that momentarily aligns with it. The unique signature of the event, which is influenced by the relative motion of the stars across space, can reveal clues to the nature of the foreground star and any associated planets. Gravitational microlensing can find cold planets in long-period orbits that other methods cannot detect. This finding opens a new piece of discovery space in the extrasolar planet hunt: to uncover planets as far from their central stars as Jupiter and Saturn are from our sun.


          Hubble Sees a 'Behemoth' Bleeding Atmosphere Around a Warm Neptune-Sized Exoplanet        

Astronomers using NASA's Hubble Space Telescope have discovered an immense cloud of hydrogen dubbed "The Behemoth" bleeding off a planet orbiting a nearby star. The enormous, comet-like feature is about 50 times the size of the parent star. The hydrogen is evaporating from a warm, Neptune-sized planet, due to extreme radiation from the star. A phenomenon this large has never before been seen around any exoplanet. It may offer clues to how Super-Earths – massive, rocky, versions of Earth – are born around other stars through the evaporation of their outer layers of hydrogen. Finding "The Behemoth" could be a game-changer for characterizing atmospheres of the whole population of Neptune-sized planets and Super-Earths in ultraviolet observations.


          Hubble Surveys Debris-Strewn Exoplanetary Construction Yards        

Over the past few years, astronomers have found an incredible diversity in the architecture of exoplanetary systems, as well as the planets themselves. A survey using the sharp view of the Hubble Space Telescope has uncovered a similar diversity in the debris systems that coincide with the formation of exoplanets. These circumstellar dusty disks are likely generated by collisions between objects left over from planet formation around stars. The survey's results suggest that there is some sort of interdependence between a planet and the accompanying debris system.


          Hubble Maps the Temperature and Water Vapor on an Extreme Exoplanet        

Located 260 light-years away, exoplanet WASP-43b is no place to call home. It is a world of extremes, where seething winds howl at the speed of sound from a 3,000-degree-Fahrenheit day side, hot enough to melt steel, to a pitch-black night side with plunging temperatures below 1,000 degrees Fahrenheit. The Hubble Space Telescope has been used to make the most detailed global map yet of the thermal glow from this turbulent world. The astronomers were also able to map temperatures at different layers of the world's atmosphere and traced the amount and distribution of water vapor. The Jupiter-sized planet lies so close to its orange dwarf host star that it completes an orbit in just 19 hours. The planet is also gravitationally locked so that it keeps one hemisphere facing the star.


          NASA Telescopes Find Clear Skies and Water Vapor on Exo-Neptune        

The weather forecast for a planet 120 light-years from Earth is clear skies and steamy water vapor. Finding clear skies on a gaseous world the size of Neptune is a good sign that even smaller, Earth-size planets might have similarly good visibility. This would allow earthbound astronomers to measure the underlying atmospheric composition of an exoplanet. Astronomers using the Hubble, Spitzer, and Kepler space telescopes were able to determine that the planet, cataloged HAT-P-11b, has water vapor in its atmosphere. The world is definitely steamy with temperatures over 1,000 degrees Fahrenheit. The planet is so hot because it orbits so close to its star, completing one orbit every five days.


          Hubble Finds Three Surprisingly Dry Exoplanets        

Astronomers using the Hubble Space Telescope have gone looking for water vapor in the atmospheres of three planets orbiting stars similar to the Sun – and have come up nearly dry. The planets spectroscopically surveyed have only one-tenth to one one-thousandth the amount of water predicted by standard planet-formation theories. The planets are not habitable because they are gaseous and are as big as Jupiter. They lie so much closer to their host star than Jupiter is to our Sun, so their atmospheres are seething between 1,500 and 4,000 degrees Fahrenheit. Nevertheless, this result suggests that some percentage of Earth-size exoplanets may be more deficient in water than predicted. And, water is a necessary prerequisite for life as we know it. The search for water-bearing terrestrial worlds may be more challenging than thought for future space telescopes. And, scientists may have to revisit their theories of planet formation.


          Hubble Sees Cloudy Super-Worlds with Chance for More Clouds        

Weather forecasters on a pair of exoplanets would have an easy job. Today's forecast: cloudy. Tomorrow: overcast. Extended outlook: more clouds. Scientists using the Hubble Space Telescope have characterized the atmospheres of two of the most common type of planets in the Milky Way galaxy and found both may be blanketed with clouds. The best guess is that the clouds are not like anything found on Earth. Their scorching atmospheres are predicted to be hundreds of degrees Fahrenheit – too hot for a rainy day.


          Hubble Traces Subtle Signals of Water on Hazy Worlds        

Astronomers continue to tally up how many planets are orbiting other stars. But finding out what their atmospheres are made of is another story. Two teams of scientists using the Hubble Space Telescope have found faint signatures of water in the atmospheres of five distant exoplanets. The planets are not the size of Earth, but rather massive worlds known as hot Jupiters because they orbit so close to their stars. Hubble's instruments can deduce the types of gases in the atmospheres of these monsters by determining which colors of a star's light are transmitted and which are partially absorbed as the planet passes in front of its star. The observations demonstrate Hubble's continuing exemplary performance in exoplanet research.

          Hubble, Swift Detect First-Ever Changes in an Exoplanet Atmosphere        

An international team of astronomers using data from the NASA's Hubble Space Telescope has made an unparalleled observation, detecting significant changes in the atmosphere of a planet located beyond the solar system. The scientists conclude that the atmospheric variations occurred in response to a powerful eruption on the planet's host star, an event observed by NASA's Swift satellite. This artist's rendering illustrates the evaporation of exoplanet HD 189733b's atmosphere in response to the powerful eruption from its host star on Sept. 7, 2011. Hubble detected the escaping gases, and Swift caught the stellar flare.

          NASA's Hubble Makes One Millionth Science Observation        

NASA's Hubble Space Telescope crossed another milestone in its 21-year space odyssey of exploration and discovery. On Monday, July 4, the Earth-orbiting observatory logged its one millionth science observation during a search for water in an exoplanet's atmosphere 1,000 light-years away. Although Hubble is best known for its stunning imagery of the cosmos, the millionth exposure is a spectroscopic measurement, where light is divided into its component colors. These color patterns can reveal the chemical composition of cosmic sources. This is an artist's concept of Hubble's millionth exposure, the extrasolar planet HAT-P-7b. It is a gas planet larger than Jupiter orbiting a star hotter than our Sun. HAT-P-7b, also known as Kepler 2b, has been studied by NASA's planet-hunting Kepler observatory after it was discovered by ground-based observations.


          Hubble Finds Hidden Exoplanet in Archival Data        

In 19 years of observations, the Hubble Space Telescope has amassed a huge archive of data. That archive may contain the telltale glow of undiscovered extrasolar planets, says David Lafrenière of the University of Toronto, Ontario, Canada. His team found the outermost of three massive planets known to orbit the young star HR 8799, which is 130 light-years away. The planetary trio was originally discovered in images taken with the Keck and Gemini North telescopes in 2007 and 2008. But using a new image processing technique that suppresses the glare of the parent star, Lafrenière found the telltale glow of the outermost planet in the system while studying Hubble archival data taken in 1998. The giant planet is young and hot, but still only 1/100,000th the brightness of its parent star (by comparison, cooler Jupiter is one-billionth the brightness of the sun).

Hubble's Near Infrared Camera and Multi-Object Spectrometer (NICMOS) has looked at over 200 other stars in coronagraphic mode, where the light of the star is largely blocked out, to search for the feeble glow of planets. Lafrenière plans to look for undiscovered planets in the NICMOS archive dataset and do follow-up observations with ground-based telescopes on any candidates that pop up. As an added bonus, NICMOS made a near-infrared measurement that suggests water vapor is in the atmosphere of the planet. This could not be easily achieved with ground-based telescopes, because water vapor in Earth's atmosphere absorbs some infrared wavelengths. Measuring the water absorption properties on this exoplanet will tell astronomers a great deal about the temperatures and pressures in the atmosphere, and about the prevalence of dust clouds. But don't go looking for beachfront property; the planet is 1,500 degrees Fahrenheit -- too hot even for water vapor clouds.


          Hubble Finds First Organic Molecule on an Exoplanet        

NASA's Hubble Space Telescope has made the first detection ever of an organic molecule in the atmosphere of a Jupiter-sized planet orbiting another star. This breakthrough is an important step in eventually identifying signs of life on a planet outside our solar system. The molecule found by Hubble is methane, which under the right circumstances can play a key role in prebiotic chemistry - the chemical reactions considered necessary to form life as we know it. This illustration depicts the extrasolar planet HD 189733b with its parent star peeking above its top edge.


          Hubble Finds that Extrasolar Planet Has a Hazy Sunset        

A team of astronomers, led by Frederic Pont from the Geneva University Observatory in Switzerland, has detected for the first time strong evidence of hazes in the atmosphere of a planet orbiting a distant star. The new Hubble Space Telescope observations were made as the extrasolar planet, dubbed HD 189733b, passed in front of its parent star in an eclipse. As the light from the star briefly passes through the exoplanet's atmosphere, the gases in the atmosphere stamp their unique spectral fingerprints on the starlight. Where the scientists had expected to see the fingerprints of sodium and potassium, there were none; implying that high-level hazes (with an altitude of nearly 2,000 miles) are responsible for blocking the light from these elements.


          Quando é que o primeiro ser humano deixará o Sistema Solar?        
Mil anos. Esse é o comprimento mínimo de tempo que levaríamos para chegar à estrela mais próxima - Proxima Centauri - usando métodos atuais.


Mas desde que descobriram que esta estrela abriga um planeta potencialmente habitável, os cientistas ficaram mais entusiasmados do que nunca com a ideia de viagens interestelares.

"É tentador", disse Guillem Anglada-Escudé, que liderou a equipe de pesquisa que descobriu o planeta,  em uma entrevista com NPR.

"Agora que sabemos que o planeta está lá, podemos ser mais criativos e pensar em soluções. Talvez enviar sondas interestelares ou projetar sondas específicas para observar este planeta"

Ainda assim, os 4,2 anos-luz que se estendem entre nós e Proxima Centauri representam uma distância assustadora para exploradores espaciais. Pode-se demorar um pouco para chegar a essas soluções. Então foi perguntado aos leitores do Futurismo sobre o quanto tempo eles acham que irá demorar até primeiro ser humano deixar o nosso sistema solar.

Não muito em breve, ao que parece. A opção que recebeu a maioria dos votos, de longe, foi o ano de 2100 ou mais tarde - esta foi a escolha de cerca de 35 por cento dos inquiridos.

Como explicou o entrevistado Charles Hornbostel, "Com a exploração humana de Marte ocorrendo não mais cedo do que o período de tempo 2025-30, é razoável esperar que os seres humanos não tenham atingido as órbitas de Netuno e Plutão até o final do século, impedindo quaisquer avanços na tecnologia de propulsão exótica ".

Hornbostel está certo sobre os muitos países e empresas que estão buscando colocar seres humanos em Marte nos próximos 10 a 15 anos.

Ele também está certo em pensar que muitos pesquisadores estão trabalhando para a criação de novas tecnologias para lançar nossas naves espaciais mais rápidas através do espaço - e especialistas têm algumas previsões.

O que os especialistas têm a dizer

Alguns entusiastas do espaço estão otimistas sobre nossas chances de viagens interestelares, argumentando que - se trabalharmos arduamente, como, agora - poderíamos chegar à Proxima Centauri até 2100.

Outros, como Marcus Young, pesquisador do Laboratório de Pesquisa da Força Aérea dos EUA, têm uma visão mais pessimista desta possibilidade. Ele disse aos participantes da Conferência Conjunta Propulsão de 2008, que sua equipe não tinha encontrado nenhuma opção viável para viagens interestelares.

"Há muitas idéias que, inicialmente, você diz, 'Ei, isso poderia funcionar'," disse Young na conferência de acordo com a Wired. "Mas depois de algumas pesquisas, você encontrará rapidamente que ele não vai."

Mas Young também argumentou que os cientistas devem continuar a estudar os problemas colocados pelas viagens interestelares. Há uma série de idéias de como podemos finalmente escapar de nosso sistema solar, incluindo foguetes foguetes de fusão, que estão sendo examinadas por uma empresa financiada pela NASA.

No entanto, a radiação destas naves provavelmente seria muito tóxica para seres humanos.

Poderíamos também usar velas solares e dar-lhes alguma potência extra, apontando lasers para elas.. Esta é a abordagem do projeto Breakthrough Starshot, mas seus objetivos são apenas enviar uma pequena sonda para o sistema Centauri, não uma nave tripulada.

E mesmo se você fosse capaz de ter uma nave espacial que consiga ir a 10 ou mesmo 20 por cento da velocidade da luz, você ainda terá o problema de prevenir danos no casco oriundos de partículas espaciais.

Você também teria que inventar maneiras de desacelerar sua velocidade, uma vez que você está próximo do sistema Centauri, apontou o fundador da SpaceX, Elon Musk, em uma entrevista com Aeon. Musk acredita que a viagem interestelar é, em última análise factível, mas um objetivo impraticável nesta fase.

"Se nós estamos próximos de ter alguma chance de enviar material para outros sistemas estelares, precisamos se tornar uma civilização multi-planetária focalizada em tecnologia laser. Esse é o próximo passo", disse Musk na entrevista.

E, se ele estiver certo, entusiastas do espaço tem uma razão para ter esperança, porque uma colônia de Marte pode estar separada apenas alguns anos de distância.

          NASA descobre 219 novos candidatos a exoplanetas - 10 deles semelhantes à Terra        


A equipe do telescópio espacial Kepler da NASA lançou um novo catálogo da missão de candidatos a planetas que apresentou 219 novos candidatos a planetas, dos quais 10 são parecidos com a Terra em tamanho e órbita nas zonas habitáveis de suas estrelas, que é o intervalo de distância de uma estrela onde a água líquida poderia fluir na superfície de um planeta rochoso.

Esta é a versão do catálogo mais abrangente e detalhada de candidatos a exoplanetas, que são planetas fora do nosso sistema solar, nos quatro anos da missão Kepler. É também o catálogo final, do ponto de vista da nave espacial do pedaço de céu na constelação de Cygnus.

Com o lançamento deste catálogo, derivado de dados publicamente disponíveis no NASA Exoplanet Archive, agora já são 4.034 candidatos a planetas identificados por Kepler, do quais, 2.335 verificados como exoplanetas e cerca de 50 desses planetas são parecidos com a Terra, de acordo com suas zonas habitável detectados pelo Kepler, e mais de 30 foram confirmados.

Além disso, os resultados dos dados do Kepler mostra dois agrupamentos de tamanho distintos de planetas pequenos. Ambos os resultados têm implicações significativas para a busca de vida. O catálogo Kepler final vai servir como a base para mais estudos para determinar a prevalência e dados demográficos de planetas na galáxia, enquanto a descoberta das duas populações planetárias distintas mostra que cerca de metade dos planetas que conhecemos na galáxia não têm qualquer superfície, ou possuem uma abaixo de sua crosta profunda, esmagada pela atmosfera - um ambiente improvável para hospedar vida.

Os resultados foram apresentados numa conferência de imprensan nesta segunda-feira, 19 de junho, no Ames Research Center da NASA no Vale do Silício, na Califórnia.

“O conjunto de dados Kepler é único, pois é o único que contém uma população de planetas análogos a Terra - planetas com aproximadamente o mesmo tamanho e órbita da Terra”, disse Mario Perez, cientista da missão Kepler e do programa na Divisão de Astrofísica  e Ciência da NASA. “Compreender a sua frequência na galáxia ajudará a informar o desenho de futuras missões da NASA a imagear diretamente outra Terra.”


O telescópio espacial Kepler caça planetas detectando a queda minúscula no brilho de uma estrela que ocorre quando um planeta passa na frente dela, o que a astronomia chama de trânsito.

Este é o oitavo lançamento do catálogo a candidatos Kepler, reunidos pelo reprocessamento todo o conjunto de dados de observações de Kepler durante os primeiros quatro anos de sua missão principal. Esta informação permitirá aos cientistas determinar quais populações planetárias - a partir de corpos rochosos do tamanho da Terra, a gigantes gasosos do tamanho de Júpiter - compõem a demografia planetárias da galáxia.

Para garantir que o número de planetas não seja perdido, a equipe apresentou seus próprios sinais de trânsito planetário simulados para o conjunto de dados e determinou quantos foram corretamente identificados como planetas. Em seguida, eles adicionaram dados que parecem vir de um planeta, mas eram realmente falsos sinais, e verificaram quantas vezes a análise confundiu estes como candidatos a planetas. Este trabalho contou-lhes que tipos de planetas estavam em excesso e quais deles foram catalogados regressivamente por métodos de processamento de dados da equipe Kepler.

“Este catálogo cuidadosamente medido é a base para responder diretamente uma das questões mais interessantes da astronomia - como muitos planetas como a nossa Terra estão na galáxia”, disse Susan Thompson, pesquisadora do Kepler para o Instituto SETI em Mountain View, Califórnia,  autor do catálogo.

Um grupo de pesquisa aproveitou os dados Kepler para fazer medições precisas de milhares de planetas, revelando dois grupos distintos de pequenos planetas. A equipe descobriu uma divisão limpa nos tamanhos dos planetas rochosos, do tamanho da Terra rochoso e planetas gasosos, menores do que Netuno. Poucos planetas foram encontrados entre esses agrupamentos.

Usando o Observatório WM Keck, no Havaí, o grupo mediu os tamanhos de 1.300 estrelas no campo Kepler para determinar o raio de 2.000 planetas com precisão requintada.

“Nós gostamos de pensar que um astrônomo catalogando planetas é como biólogos identificando novas espécies de animais”, disse Benjamin Fulton, doutorando na Universidade do Havaí em Manoa, e principal autor do segundo estudo. “Encontrar dois grupos distintos de exoplanetas é como descobrir mamíferos e lagartos em ramos distintos de uma árvore de família.”

Parece que a natureza comumente fazem planetas rochosos até cerca de 75 por cento maior que a Terra. Por razões que os cientistas ainda não compreendem, cerca de metade desses planetas assumem uma pequena quantidade de hidrogênio e hélio que aumenta dramaticamente seu tamanho, o que lhes permite "saltar o fosso" para fazer parte da população mais próxima ao tamanho de Netuno.

A sonda Kepler continua a fazer observações em novos remendos do céu em sua missão estendida, em busca de planetas e uma variedade de objetos astronômicos interessantes, a partir de aglomerados de estrelas distantes para objetos como a TRAPPIST-1, o sistema de sete planetas do tamanho da Terra mais próximo de casa.

          Astrônomo diz que nós encontraremos vida alienígena dentro da próxima década        
De cientistas altamente treinados labutando em institutos de pesquisa à entusiastas amadores olhando para cima de seus quintais, a humanidade está cheia de pessoas à procura de vida fora da Terra.

Acrescente a isso o enorme tamanho do Universo - as estimativas variam em  trilhões de galáxias  - e probabilidade que devemos já ter encontrado outra espécie até agora. E, no entanto, ainda não temos nenhuma evidência de que não estamos sozinhos no Universo.

No entanto, de acordo com o astrônomo Chris Impey, esta caça à vida fora da Terra em breve poderá produzir resultados.

Em uma entrevista para o futurism, ele revelou que ele acredita que estamos a menos de duas décadas de encontrar vida extraterrestre... mas pode não ser o tipo de vida que esperávamos: "Eu coloco minhas apostas que encontraremos vida microbiana em 10 a 15 anos, mas não aposto em vida inteligente."

Enquanto Impey é cético de que vida inteligente está dentro de nossas vistas, e tem duas sugestões de onde devemos concentrar nossa busca por formas de vida extraterrestres, inteligentes ou não. A primeira é o nosso próprio quintal, ou, mais precisamente, o nosso próprio Sistema Solar.

Impey disse que não descarta a possibilidade de que a vida ainda exista em Marte, e diz que essas formas de vida são susceptíveis abaixo da superfície e são, portanto, muito mais difíceis de detectar.

Como tal, ele afirma que temos uma melhor chance de encontrar evidências de vida que existia no planeta vermelho: "Se nós realmente conseguirmos trazer rochas de Marte de volta aqui para a Terra de um lugar que nós acreditamos que poderia ter sido habitável no passado, então poderemos encontrar evidências de vida antiga."

Outros corpos no nosso Sistema Solar poderiam abrigar vida, de acordo com Impey, incluindo Europa (uma das várias luas de Júpiter).

Ele acha que as missões futuras visando o satélite poderiam ser úteis - se não totalmente conclusivas - afirmando que eles deverão, pelo menos, dar-nos "alguma ideia melhor se esse oceano poderia ter vida."

Naturalmente, o nosso Sistema Solar é apenas um pequeno canto de um Universo muito grande, de modo que seria negligente se não olhar para além dele para buscar sinais de vida.

Para restringir o escopo da pesquisa, Impey sugere visar a muitas exo-Terras que já descobrimos. Em vez de focar nas superfícies dos planetas, porém, devemos pesquisar suas atmosferas.

Nos próximos anos, vamos ser capazes de usar o telescópio espacial James Web e outros dispositivos de detecção para procurar biomarcadores tais como oxigênio e metano na atmosfera desses planetas como a Terra, diz Impey.

"Este biomarcador poderia encontrar evidências de vida microbiana indiretamente", explica ele.

A pesquisa deve nos ajudar a identificar os planetas que estão "o mais próximo da Terra quanto possível, não na distância, mas em caráter", acrescenta ele, e uma vez que a Terra é o único lugar que sabemos que existe vida, encontrar o maior número de planetas como a Terra é nossa melhor aposta para encontrar vida.

Mesmo se Impey estiver certo, e a humanidade ainda está a décadas de distância de encontrar vida inteligente extraterrestre, a descoberta de vida microbiana em Marte, Europa, ou um dos milhares de exoplanetas que identificamos ainda seria um grande desenvolvimento.

Isso significaria que a Terra não é única, e que a vida existe lá fora.

Nós poderíamos usar o conhecimento que recolher de estudar esta vida microbiana para diminuir a nossa caça para outros organismos mais complexos.

Ao fornecer informações valiosas sobre como os outros seres vivos são capazes de sobreviver em mundos muito diferentes do nosso, esta vida microbiana poderia ajudar em nossa busca para se tornar uma espécie multi-planetária.

Mesmo a descoberta da vida microbiana passada é útil, uma vez que poderia servir como algo de um conto preventivo, fornecendo-nos a oportunidade de aprender e garantir para que não encontramos o mesmo destino.

Como observa Impey, graças a avanços dramáticos na tecnologia, nós nunca estivemos melhor equipados para descobrir vida fora da Terra como agora: "Cada nova experiência do SETI feita agora é quase tão boa quanto a soma de todos os experimentos do SETI anteriores juntos".

No entanto, mesmo se todos os experimentos e missões atualmente planejadas forem curtas, Impey não prevê que a humanidade desista da busca por vida extraterrestre:

"O primeiro experimento do SETI foi em 1959, então obviamente ele já se arrasta há mais de meio século sem qualquer sucesso. As pessoas que fazem isso não parecem colocar-se fora pelo fracasso."

          7 earth-size planets identified in orbit around a dwarf star        
Not just one, but seven Earth-size planets that could potentially harbor life have been identified orbiting a tiny star not too far away, offering the first realistic opportunity to search for biological signs of alien life outside of the solar system. The planets orbit a dwarf star named Trappist-1, about 40 light years, or about 235 trillion miles, from Earth. That is quite close, and by happy accident, the orientation of the orbits of the seven planets allows them to be studied in great detail. One or more of the exoplanets - planets around stars other than the sun - in this new system could be at the right temperature to be awash in oceans of water, astronomers said, based on the distance of the planets from the dwarf star. Science is awesome.
          YSO FAQ        

Here we hope to answer some of the questions observers ask about YSOs. If there is anything that isn't covered in the points below, why not drop me an email?

What is the T Tauri Wind?

Comparisons are often made between how stars grow and how humans grow. Thinking of YSOs as baby stars, it's tempting to say that stars suffer from wind as well! But it's nothing to do with flatulence. It seems that it's an integral part of the star formation process. What happens is that as the star draws down gas from the accretion disc it grows to a point where pressure causes the star to 'turn on' by fusing Hydrogen. The radiation pressure blows a great deal of the star's mass out of its poles (the points of least resistance) and this is the T Tauri wind. These jets escape in the form of 3-dimensional fans (right) which is why many YSOs appear to be attended by fan-shaped nebulae; the nebula is not actually that shape, it's just that parts of it are being illuminated by the 'T Tauri fans' which take various forms depending on how they are presented to us. T Tauri winds lead nicely into the next question...

What's a Herbig-Haro Object?

The polar jets aren't content to rest on their laurels - they have interesting effects on the surrounding environment as well. The energetic material, and the radiation, blasts into the gas cloud from which the star formed, and can actually set off more star formation. These jets can be several light-years in length and many are visible to us. These are called Herbig-Haro Objects after the astronomers who first called attention to them. Sometimes we can see the whole thing - the dark disc (no longer hot enough to shine but still opaque enough to hide the actual star) the polar jets and an illuminated nebula. The picture here is the environment of DG Tau (we have a chart for it!) and the scale at bottom right is 200 AU, which gives you some idea of the size of the disc. Note how the brightness of the 'fans' falls off with distance. Here we are looking practically equator-on to the system. A google search for images of H-H objects will quickly demonstrate that they come in all shapes and sizes, since nearby stars - which may themselves be forming - can affect the shape of the jets.

Why should I observe them?

Lots of reasons:
They are interesting, and even exciting! Some show extremely rapid variations, every bit as rapid as U Gem stars, sometimes even more so.
Professional astronomers are interested in them. YSOs can provide most of the information about how planetary systems form, which naturally has implications for the search for exoplanets, life in the universe, and so on.

But aren't they faint and obscure? I've only got a 6" newtonian!

Some are, of course. But with your 6" scope you could observe some really interesting and active stars like CQ tau, RW Aur, YZ Cep and many others. AB Aurigae is visible with binoculars at all times!

 

 


          Keajaiban Bintang Sirius, Saksi Kebenaran Miraj Nabi Muhammad saw        
Sirius adalah bintang paling terang dilangit malam apabila dilihat dari bumi. Terletak di rasi bintang Canis Major dan merupakan sebuah tata surya yang hanya memiliki dua bintang saja (bintang kembar), yaitu Sirius A dan Sirius B.

Rasi bintang Canis Major, tempat dimana bintang Sirius berada.

Bintang Sirius A dapat dilihat hampir disemua permukaan bumi dan saat terbaik untuk melihat bintang ini adalah pada tanggal 1 Januari dimana tepat berada di atas langit pada pukul dua belas malam. Berbeda dengan pasangannya, Sirius B sangatlah redup sehingga tidak dapat dilihat  dengan mata telanjang meskipun dalam kondisi langit yang cerah di malam hari. 

Ilustrasi lebih dekat Bintang Sirius A dan Sirius B

Penampakan Sirius B jika diperbesar dengan teleksop luar angkasa.
Sirius B akan sulit dilihat jika tidak menggunakan teleskop super canggih.

Dalam sejarahnya nama bintang ini memiliki beberapa nama seperti dalam bahasa Yunani disebut Σείριος (Seirios, yang berarti "menyala-nyala" atau "amat panas"), dalam bahasa Latin disebut Canicula ("anjing kecil") dan dalam bahasa Arab disebut aÅ¡-Å¡yi‘rā (الشعرى)  dalam astronomi Islam, dimana nama alternatif Al Shira diturunkan . 

Sistem orbit bintang ini mengelilingi satu sama lain membentuk busur panah ganda. Lama satu siklus orbit bintang ini adalah 49,9 tahun. Angka ini disahkan oleh jurusan astronomi di Universitas Harvard, Ottawa dan Leicester . Penjelasan ini dijelaskan dari berbagai sumber sebagai berikut:
Sirius, bintang yang paling terang, sebenarnya adalah bintang kembar… 
Peredarannya berlangsung selama 49,9 tahun. 
(Exposes Astronomiques, La troisième loi de KEPLER)

Sebagaimana diketahui, bintang Sirius-A dan Sirius-B beredar mengelilingi satu sama lain melintasi sebuah busur ganda setiap 49,9 tahun.
(www.dharma.com.tr; www.exoplaneten.de)

Orbit bintang Sirius A dan B berbentuk elips satu dengan yang lainnya seperti dua busur panah

Bintang Sirius dalam Al Quran

Hal yang menarik untuk dikaji adalah bintang Sirius atau Syi’ra merupakan satu-satunya nama bintang selain matahari yang disebutkan dalam Al Quran pada surat An Najm.
dan bahwasanya Dialah yang Tuhan (yang memiliki) bintang syi'ra. 
(QS. An Najm, 49)
Namun ada yang menarik pada ayat sebelumnya di surat yang sama, yaitu sebagai berikut:
maka jadilah dia dekat dua ujung busur panah atau lebih dekat (lagi). 
(QS. An Najm, 9)
Pada pemaparan sebelumnya telah disinggung bahwa bintang Sirius merupakan bintang yang mengorbit satu sama lain dengan membentuk dua busur panah.  Perhatikanlah ayat Al Quran diatas, sangatlah cocok seperti apa yang di jelaskan dalam Al Quran yaitu membentuk dua ujung busur panah.
Kajaiban yang lainnya ialah lama edar orbit kedua bintang ini. Kedua bintang ini mengelilingi satu sama lain melintasi satu siklus orbit yang membentuk busur ganda setiap 49,9 tahun. 
Orbit bintang Sirius A (biru), Sirius B (kuning) beredar mengelilingi satu sama lain selama 49,9 tahun
Perhatikanlah kedua ayat Al Quran yang berhubungan dengan bintang Syi'ra berikut:
dan bahwasanya Dialah Tuhan (yang memiliki) bintang Syi'ra 
(QS. An Najm, 49)
maka jadilah dia dekat dua ujung busur panah atau lebih dekat (lagi). 
(QS. An Najm, 9)
Gabungkanlah kedua ayat diatas, yaitu ayat 49 dan ayat 9 dengan ditambahkan koma diantara angka tersebut, maka akan membentuk angka 49,9. Sama seperti lama peredaran bintang ini satu sama lain, yaitu 49,9 tahun.
Subhanallah, Maha Benar Allah Atas Segala Firman-Nya.

Bintang Sirius Adalah Saksi Miraj Nabi Muhammad saw

Saksi mata sangat dibutuhkan untuk membenarkan sebuah perkara. Di pengadilan misalnya, kesaksian yang didukung saksi mata, akan lebih diterima Hakim dibanding kesaksian tanpa saksi mata. Bahkan seseorang yang dianggap benar, tapi tidak dapat mengajukan saksi mata, di pengadilan dapat menjadi pihak yang kalah.
Dalam Islam seluruh manusia akan dipertanggungjawabkan amal perbuatannya di akhirat kelak, Allah akan menjadikan lidah, tangan dan kaki sebagai saksi terhadap segala sesuatu yang dikerjakan di dunia. Sebagaimana Firman Allah swt :
“Pada hari (ketika) lidah, tangan, dan kaki mereka menjadi saksi atas mereka terhadap apa yang dahulu mereka kerjakan. Di hari itu, Allah akan memberi mereka balasan yang setimpal menurut semestinya, dan tahulah mereka bahwa Allah-lah yang benar lagi yang menjelaskan (segala sesuatu menurut hakikat yang sebenarnya).” (Qs. An-Nur: 24-25)
Dalam Islam, saksi bukan hanya makhluk hidup tetapi apa yang kita anggap sebagai benda mati pun akan dimintai sebagai saksi oleh Allah swt sehingga nanti manusia tidak bisa mengelak jika berdusta. Disinlah Allah menjadikan bintang Sirius sebagai argumentasi dan saksi kebenaran Miraj Nabi Muhammad saw, selain itu surat An Najm (berarti Bintang) jika dibaca ayat per ayat merupakan kronologis perjalan Miraj Nabi ke Sidratul Muntaha (tempat tertinggi di langit).
“Sedang Dia berada di ufuk yang tinggi. Kemudian Dia mendekat, lalu bertambah dekat lagi.
Maka jadilah Dia dekat (pada Muhammad sejarak) dua ujung busur panah atau lebih dekat (lagi). Lalu Dia menyampaikan kepada hamba-Nya (Muhammad) apa yang telah Allah wahyukan. Hatinya tidak mendustakan apa yang telah dilihatnya. Maka apakah kaum (musyrik Mekah) hendak membantahnya tentang apa yang telah dilihatnya? Dan sesungguhnya Muhammad telah melihat Jibril itu (dalam rupanya yang asli) pada waktu yang lain. (yaitu) di Sidrat al-Muntaha. Di dekatnya ada surga tempat tinggal. (Muhammad melihat Jibril) ketika Sidrat al-Muntaha diliputi oleh sesuatu yang meliputinya. Penglihatannya (Muhammad) tidak berpaling dari yang dilihatnya itu dan tidak (pula) melampauinya. Sesungguhnya Dia telah melihat sebahagian tanda-tanda (kekuasaan) Tuhannya yang paling besar.” 
(QS al-Najm [53]: 7-18)
Dalam kasus Bintang Sirius sebagai saksi kebenaran Miraj Nabi sudah jelas bahwa tempat pertemuan Nabi Muhammad saw di langit dengan malaikat Jibril adalah pada sejarak dua ujung busur panah (bintang Sirius), dengan begitu bagi siapapun yang tidak percaya akan Isra Miraj Nabi Muhammad saw mereka adalah orang yang berdusta. Disinlah keajaiban Al Quran tentang bintang Sirius, Allah menerangkan orbit bintang Sirius padahal 1400 tahun yang lalu tidak ada yang mengetahui bahwa orbit bintang ini berbentuk dua ujung busur panah setiap 49,9 tahun, tetapi Al Quran sudah menggunakannya dengan bahasa sains modern yang sangat mudah dipahami.
Perhatikanlah sekali lagi ayat Al Quran berikut :
dan bahwasanya Dialah Tuhan (yang memiliki) bintang Syi'ra 
(QS. An Najm, 49)
maka jadilah dia dekat dua ujung busur panah atau lebih dekat (lagi). 
(QS. An Najm, 9)

Saturn: Four Rings

Walter A. Feibelman of the University of Pittsburgh … has found evidence indicating a fourth ring [of Saturn].… Every 14.78 years, the rings of Saturn can be seen edge-on from Earth, and the past winter marked one of these opportunities.… The thin ring “extends to more than twice the known ring diameter” (or a total of 340,000 miles), and is so faint it cannot be photographed except with a large telescope. — Science News, June 3, 1967

Update

 Scientists no longer observe Saturn’s rings only from Earth. Four spacecraft have visited the planet and revealed a complex ring system, with the four previously known rings accompanied by multiple fainter ones. NASA’s Cassini spacecraft, which arrived at the planet in 2004, is now swooping between Saturn and its rings to get the closest views yet (SN Online: 4/27/17). Rings have also been spied around Jupiter, Uranus and Neptune, and in 2012, scientists spotted an exoplanet with giant rings (SN: 3/7/15, p. 5).

          Top 10 science anniversaries of 2017         

It’s time to celebrate pulsars, planets, Einstein, more Einstein and the laws of robotics

Context
Jocelyn Bell Burnell

This year marks the semicentennial of the discovery of pulsars, first observed by Jocelyn Bell Burnell, shown here in 1968 at the Mullard Radio Astronomy Observatory in Cambridge, England.

Second of two parts

Every year science offers a diverse menu of anniversaries to celebrate. Births (or deaths) of famous scientists, landmark discoveries or scientific papers — significant events of all sorts qualify for celebratory consideration, as long as the number of years gone by is some worthy number, like 25, 50, 75 or 100. Or simple multiples thereof with polysyllabic names.

2017 has more than enough such anniversaries for a Top 10 list, so some worthwhile events don’t even make the cut, such as the births of Stephen Hawking (1942) and Arthur C. Clarke (1917). The sesquicentennial of Michael Faraday’s death (1867) almost made the list, but was bumped at the last minute by a book. Namely:

10. On Growth and Form, centennial (1917)

A true magnum opus, by the Scottish biologist D’Arcy Wentworth Thompson, On Growth and Form has inspired many biologists with its mathematical analysis of physical and structural forces underlying the diversity of shapes and forms in the biological world. Nobel laureate biologist Sir Peter Medawar praised Thompson’s book as “beyond comparison the finest work of literature in all the annals of science that have been recorded in the English tongue.”

9. Birth of Abraham de Moivre, semiseptcentennial (1667).

Born in France on May 26, 1667, de Moivre moved as a young man to London where he did his best work, earning election to the Royal Society. Despite exceptional mathematical skill, though, he attained no academic position and earned a meager living as a tutor. He is most famous for his book The Doctrine of Chances, which was in essence an 18th century version of Gambling for Dummies. It contained major advances in probability theory and in later editions introduced the concept of the famous bell curve. Isaac Newton was impressed; the legend goes that when anyone asked him about probability, Newton said to go talk to de Moivre.

8. Exoplanets, quadranscentennial (1992)

It seems like exoplanets have been around almost forever (and probably actually were), but the first confirmed by Earthbound astronomers were reported just a quarter century ago. Three planets showed up orbiting not an ordinary star, but a pulsar, a rapidly spinning neutron star left behind by a supernova.

Astrophysicists Aleksander Wolszczan and Dale Frail found a sign of the planets, first detected with the Arecibo radio telescope, in irregularities in the radio pulses from the millisecond pulsar PSR1257+12. Some luck was involved. In 1990, the Arecibo telescope was being repaired and couldn’t pivot to point at a specific target; instead it constantly watched just one region of the sky. PSR1257+12 just happened to float by.

7. Birth of Marie Curie, sesquicentennial (1867)

No doubt the most famous Polish-born scientist since Copernicus, Curie was born in Warsaw on November 7, 1867, as Maria Sklodowska. Challenged by poverty, family tragedies and poor health, she nevertheless excelled as a high school student. But she then worked as a governess, while continuing as much science education as possible, until her married sister invited her to Paris. There she completed her physics education with honors and met and married another young physicist, Pierre Curie.

Together they tackled the mystery of the newly discovered radioactivity, winning the physics Nobel in 1903 along with radioactivity’s discoverer, Henri Becquerel. Marie continued the work after her husband’s tragic death in 1906; she became the first person to win a second Nobel, awarded in chemistry in 1911 for her discovery of the new radioactive elements polonium and radium.

6. Laws of Robotics, semisesquicentennial (1942)

One of science fiction’s greatest contributions to modern technological philosophy was Isaac Asimov’s Laws of Robotics, which first appeared in a short story in the March 1942 issue of Astounding Science Fiction. Later, those laws formed the motif of his many robot novels and appeared in his famous Foundation Trilogy (and subsequent sequels and prequels). They were:

  1. A robot may not injure a human being or, through inaction, allow a human being to come to harm.
  2. A robot must obey the orders given to it by human beings, except where such orders would conflict with the First Law.
  3. A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.

Much later Asimov added a “zeroth law,” requiring robots to protect all of humankind even if that meant violating the other three laws. Artificial intelligence researchers all know about Asimov’s laws, but somehow have not managed to enforce them on social media. Incidentally, this year is also the quadranscentennial of Asimov’s death in 1992.

5. First sustained nuclear fission chain reaction, semisesquicentennial (1942)

Enrico Fermi, the Italian Nobel laureate, escaped fascist Italy to come to the United States shortly after nuclear fission’s discovery in Germany. Fermi directed construction of the “atomic pile,” or nuclear reactor, on a squash court under the stands of the University of Chicago’s football stadium. Fermi and his collaborators showed that neutrons emitted from fissioning uranium nuclei could induce more fission, creating a chain reaction capable of releasing enormous amounts of energy. Which it later did.

4. Discovery of pulsars, semicentennial (1967)

Science’s awareness of the existence of pulsars turns 50 this year, thanks to the diligence of Irish astrophysicist Jocelyn Bell Burnell. She spent many late-night hours examining the data recordings from the radio telescope she helped to build that first spotted a signal from a pulsar. She recognized that the signal was something special even though others thought it was just a glitch in the apparatus. But she was a graduate student so her supervisor got the Nobel Prize instead of her. 

3. Einstein’s theory of lasers, centennial (1917)

Albert Einstein did not actually invent the laser, but he developed the mathematical understanding that made lasers possible. By 1917, physicists knew that quantum physics played a part in the working of atoms, but the details were fuzzy. Niels Bohr had shown in 1913 that an atom’s electrons occupy different energy levels, and that falling from a high energy level to a lower one emits radiation.

Einstein worked out the math describing this process when many atoms have electrons in high-energy states and emit radiation. His analysis of matter-radiation interaction indicated that it would be possible to prepare many atoms in the same high-energy state and then stimulate them to emit radiation all at once. Properly done, all the atoms would emit radiation of identical wavelength with the waves in phase. A few decades later other physicists figured out how to build such a device for use as a powerful weapon or to read bar codes at grocery stores.

2. Qubits, quadranscentennial (1992)

An even better quantum anniversary than lasers is the presentation to the world of the concept of quantum bits of information. Physicist Ben Schumacher of Kenyon College in Ohio unveiled the idea at a conference in Dallas in 1992 (I was there). A “quantum bit” of information, or qubit, represents the information contained in a quantum particle, which can exist in multiple states at once. A photon, for instance, might simultaneously be in a state of horizontal or vertical polarization. Or an electron’s spin could be up and down at the same time.

Such states differ from classical bits of information in a computer, recorded as either a 0 or 1; a quantum bit is both 0 and 1 at the same time. It becomes one or the other only when observed, much like a flipped coin is nether heads nor tails until somebody catches it, or it lands on the 50 yard line. Schumacher’s idea did not get a lot of attention at first, but it eventually became the foundational idea for quantum information theory, a field now booming with efforts to construct a quantum computer based on the manipulation of qubits.

1. Birth of modern cosmology, centennial (1917)

It might seem unfair that Einstein gets two Top 10 anniversaries in 2017, but 1917 was a good year for him. Before publishing his laser paper, Einstein tweaked the equations of his brand-new general theory of relativity in order to better explain the universe (details in Part 1). Weirdly, Einstein didn’t understand the universe, and he later thought the term he added to his equations was a mistake. But it turns out that today’s understanding of the universe’s behavior — expanding at an accelerating rate — seems to require the term that Einstein thought he had added erroneously. But you can’t expect Einstein to have foreseen everything. He probably had no idea that lasers would revolutionize grocery shopping either.

          Observational evidence for two distinct giant planet populations        

Vol. 603
In section 10. Planets and planetary systems

Observational evidence for two distinct giant planet populations

by N.C. Santos, V. Adibekyan, P. Figueira, et al. A&A 603, A30


alt

Giant planets are thought to form in circumstellar disks, while brown dwarfs and stars are thought to form directly by gravitational collapse and fragmentation of a gas cloud. We do not know how efficient these mechanisms are, whether they overlap in mass and whether other mechanisms also exist. Santos et al. provide observational evidence for the existence of two distinct populations of planets/brown dwarfs: objects with masses smaller than approximately four Jupiter masses show a strong preference for metal-rich stars. At larger masses, between 4 and 20 Mjup, this preference disappears, indicating that these brown dwarfs/massive giant planets formed with a different mechanism. Although the mechanisms themselves remain to be identified, statistical studies of the population of exoplanets are beginning to shed light on their formation.

          266 - Anchor's Away, Part 1        

00:00:00 - Something a little different this week as Ryan presents some audio from a project he did with the startup Anchor.fm earlier this year producing some science segments for a channel called Organized Curiosity. He's drinking a Manta Ray from Ballast Point Brewing Company, which will become relevant later, but for now, here are the topics that get covered:

00:03:40 - First up, an explanation of the station and why I chose the name Organized Curiosity. (Spoiler: It's from a quote in Zora Neale Hurston's autobiography)
00:07:14 - Better know a root: astro-

00:24:46 - Bio bios: Indian vulture (Gyps indicus)
00:29:56 - News you probably cannot use: NASA announces new exoplanets

00:37:58 - Bio bios: Pygmy devilray (Mobula eregoodootenkee)
00:42:53 - News you probably cannot use: What the deep ocean sounds like
00:47:01 - Bio bios: Gemsbok (Oryx gazella)
00:50:19 - Q&A: How do animals know what to do? 
00:56:03 - Finally, we end with a quick PaleoPOW thanking Billy Nitro for his recurring PayPal donation and his sweet sweet radio voice. Thanks, Billy!

          Ep 222: Science... sort of - Methane, not even once        

00:00:00 - Everyone out there wants to find alien life right? I mean, as pop culture has shown us over and over again, this will definitely work out well for humanity. Well one way we might find other intelligent life is if we use this new fancy James Webb telescope to look for their pollution in the atmosphere. To think all those years of polluting our own planet might finally pay off...

 

00:26:39 - Worried about polluting our planet to the point where we can no longer survive on it? Stop worrying and have a beer instead. Charlie has a seasonal Irish red from Boundary Bay Brewing, which leads to a rant about hops. Joe, who has had an IPA once before, but instead grabbed a "weird" Sangria Senorial, which does not have alcohol despite the name. Ryan consoles himself with an aged Raspberry Russian Imperial Stout from Widmer Bros.

 

00:34:00 - Did you know the moon Titan has seas made of farts? Well it does. The question then becomes, how do you get a submarine to function in liquid methane? NASA has some ideas, and the Paleopals expound with some of their own.

 

00:56:51 - PaleoPOWs are a lot like submarines on other planets, you're not sure if they'll work and you won't know until it's too late to do anything about it. Nicole D. definitely thinks its working out because she setup a new recurring donation to support the show. Thanks, Nicole! Another Nicole has a question from a "coworker" about whether or not you could freeze a human so fast that they shatter. Charlie does some math and the answer may surprise you! Finally, RJ from Topeka wants to know if we think robots are actually alive. Again, the answer may surprise you! Also, listen to our interview with Daniel H. Wilson and then watch The Imitation Game.

00:00:00 - Like a modern day Cassandra, scientists have long predicted that insects would catch up to our GMO crops. Now, even though the biotech companies did their best to keep it hidden, corn rootworms have infested the US corn supply. Thanks for not even pretending to listen.

 

00:23:28 - Ryan has a riff on a Cuba Libre known as a Cubata using actual Cuban rum. Abe and Ryan manage to make sense of Abe's My Antonia from Dogfish Head. And Charlie has a terroir-agnostic Pleiades blend red wine.

 

00:34:24 - The tech-nerd rapture knowns as the Singularity comes under scrutiny both as a concept and as a plotline when the guys watch the preview of Transcendence in this week's Trailer Trash Talk!

 

00:54:07 - Y'know that big thing up in the sky? No, the other one. The nighttime one. Well for a long time we thought it was as necessary as the daytime sky object (aka the Sun) but mayhaps life can evolve without a stabilizing moon. Doesn't mean we don't still love ya, moon!

 

01:17:45 - PalePOWs are a lot like moons. We only go their occasionally and seldom return. Abe starts us off with a donation from Michael S. Thanks, Michael! Charlie has a nice comment from active Irishman Liam O'Grady, reminding us of our very first Special Edition episode. And Ryan fields a question from Bobbi B. about the nature of dinosaur herds and the shape of human penises, based on some stuff said during his hijacking of The Weekly Weinersmiths. Maybe listen to that part using headphones.

          Ep 194: Science... sort of - Hot and Sour        

00:00:00 - Whether they formed via troll warfare or via geology, all we know now is that Iceland is covered in lava tubes. A possible explanation for their enigmatic origin is tonight's first topic!

 

00:18:47 - We presume that trolls like to drink, so in some ways this segment is for them. But it's also for you, the listener. And us. Definitely for us. Ryan continues his tour of Panamanian beers with a Soberana, which has nothing to do with sobreity nor frogs. Charlie enjoys some silky smooth Scotch and Abe keeps things thematic with a Hop Lava imperial IPA.

 

00:25:39 - Another 'historical' figure who liked to drink was Noah, and we discuss his upcoming eponymous movie, along with other aspects of his myth, in this week's Trailer Trash Talk!

 

00:41:10 - A coral reef has been found thriving in an acidified section of ocean. Does this mean all that worry over climate change was for naught? NAY! The Paleopals are here to set the record straight and explain what this seeming conundrum actually says about our ever-changing globe.

 

00:51:19 - PaleoPOWs are a lot like acid, too much and they burn, but just enough and they give you a pleasant sourness. Charlie begins with an e-mail from Andrew H. about a new planet that shakes up some of the ways we thought planets formed. Ryan thanks Brandon W. for a donation. Thanks, Brandon! And Abe, whom you can now follow Twitter, reads an iTunes review from Whip Hubley.

00:00:00 - New planets may be starting to seem like old hat, but this time we're using Ben's favorite fundamental force, gravity, to find them! Charlie also enlightens us on the BEER method for detecting planets.

00:14:55 - Speaking of BEER... Ben has a grass jelly drink, which brings up the topic of hippos spraying their poop somehow. Ryan is enjoying a Cerahopsian IPA given to him by Paloeposse member extraordinaire, Danielle. N. Thanks, Danielle! And Charlie is having an appropriately titled Stark Raving Red wine.

00:20:28 - Revelations as surprising as those made in the story itself are discussed alongside the trailer for the controversial Ender's Game.

00:36:43 - Given the right circumstances, you can turn your own digestive system into a very tiny brewery, which is exactly what has happened to one man in Texas.

00:49:44 - PaleoPOWs are a lot like breweries, they smell like bread and are lots of fun. Ben has a question from Luke J. about the mechanics surrounding Krypton's distance from Earth, including Neil DeGrasse Tyson's contribution to that mythos. Ryan presents a new iTunes review AND a recurring donation from Dave M. Thanks for being a double-threat, Dave! Charlie answers a question from Amy H. about tidal locking, with some contribution from Ben.

00:00:00 - Amateur astronomers have been pouring over a cloud on Mars. What could it be? No one is quite sure, but no matter what it's a game-changer for the red planet.

00:16:55 - Mars may be dry but the Paleopals are not. Charlie has an IPA that would be good if not for a better one earlier in the week. Ryan cracks open a microbrew in a tallboy. And Kelly supports gay rights with a decaf Starbucks coffee.

00:22:49 - This week's Trailer Trash Talk is on the trail of a The Hunter, a new movie about looking for Tasmanian tigers amidst intrigue and drama. The Paleopals also spend some time talking about Thylacines and marsupials in general.

00:36:15 -  For awhile the Universe was missing mass. An Australian student finally looked in the largest objects ever known and found it. What were the odds?

00:48:28 - PaleoPOWs are a lot like galactic filaments; they both take up more space than expected. Ryan has a new recurring donation for Abigail A. Thanks, Abigail! Charlie answers a question about exoplanetary atmospheres and Goldilocks zones from Corey B. And finally Kelly has a website comment from Chelsea R. letting us know Ep 127 may be her favorite yet!

          Científicos proponen un nuevo protocolo para contactar con extraterrestres        

Los astrofísicos encargados de analizar las posibles señales extraterrestres y de diseñar los mensajes que la humanidad envía al espacio han llegado a la conclusión de que necesitamos elaborar mejores protocolos para contactar con alguien más allá de la Tierra. Desde 1974 hemos transmitido mensajes dirigidos a posibles civilizaciones extraterrestres, pero quizás han sido demasiado complejos como para que puedan ser comprendidos. El protocolo METI (Messaging to Extraterrestrial Intelligence) podría ser la solución a este problema.

La humanidad ha desarrollado varios programas destinados a contactar con posibles inteligencias extraterrestres. Quizás los proyectos más famosos sean los discos de oro que viajan a bordo de las sondas Voyager, conocidos como ”Sound of Earth” o “Sonidos de la Tierra", discos de gramófono en los que se incluyen algunas decenas de sonidos y más de imágenes características de nuestro planeta; y las emisiones de mensajes de radio a través del radiotelescopio de Arecibo, en Puerto Rico, desde 1974.

Se trata de proyectos que han sido diseñados por científicos brillantes, pero algunos de sus colegas creen que pueden ser demasiado complejos y crípticos como para que extraterrestres que los reciban puedan comprender el mensaje. ¿Alguien puede imaginarse a ET -que quizás ni siquiera tenga algo parecido al sentido del oído- construyendo un gramófono para reproducir y luego interpretar el canto de una ballena terrestre? De esas dificultadas estamos hablando.

Pero un trío de reconocidos astrofísicos provenientes de los Estados Unidos y Francia -Dimitra Atri, Julia DeMarines y Jacob Haqq-Misra- tienen la esperanza de modificar esta situación, poniendo a punto un protocolo más simple y comprensible, que pueda ser utilizado como base para el intercambio de mensajes con posibles civilizaciones extraterrestres. El protocolo, denominado METI (Messaging to Extraterrestrial Intelligence) tiene en cuenta diversos factores, como la forma en que se codifica la señal que contiene el mensaje, la longitud del mismo, y lo más importante: su contenido.

METI, tal como lo explica el astrónomo de la Universidad de Kansas, Dimitra Atri, contempla utilizar longitudes de onda específicas para la transmisión: 1,42 GHz y 4,46 GHz, que se encuentran habitualmente en las emisiones electromagnéticas naturales -la primera, por ejemplo, corresponde a la frecuencia natural de resonancia del hidrógeno- y resultarían más simples de captar por razas extraterrestres que sólo dispongan de una "modesta capacidad técnica". También recomiendan establecer una suerte de “faro de transmisión” dedicado a la emisión de mensajes con una programación periódica.

Una inteligencia artificial

Al igual que buena parte de la comunidad de radioastrónomos, estos tres científicos coinciden con Seth Shostak -astrónomo de SETI- en que también deben modificarse los enfoques actuales para que contemplen la búsqueda de máquinas inteligentes. Si la tecnología de ET se parece a la nuestra, en algún punto de su desarrollo construirán máquinas lo suficientemente avanzadas como para que puedan evolucionar por sí mismas, posiblemente sobreviviendo a la especie que las creó. Esas máquinas podrían estar allí afuera, y -luego de discutir la conveniencia de ser detectadas por ellas- necesitamos un protocolo adecuado para entendernos con una inteligencia artificial.

Pero la principal crítica que Atri y sus colegas hacen de los sistemas implementados hasta la fecha es que son excesivamente antropocéntricos: difícilmente una criatura de nueve extremidades que viva en el sistema Gliese podría entender los matices humanos que poseen las imágenes terrestres. Aún teniendo la habilidad técnica y la pericia necesaria para decodificar e interpretar una colección de bits como una imagen, difícilmente puedan captar la sutileza que posee una fotografía que muestra un lobo y un cordero que pretende representar el bien y el mal.

"Sabemos muy poco sobre la naturaleza de las civilizaciones extraterrestres. Si existen, es probable que podamos incrementar la probabilidad de comunicarnos correctamente con ellos si utilizamos un mensaje que el destinatario pueda entender", dicen los autores del trabajo. Para ello proponen realizar una prueba a nivel mundial del nuevo protocolo METI, para determinar si todas las culturas de la Tierra pueden entenderlo. La idea no es mala, ya que si nosotros mismos tenemos dificultades para entender lo que estamos diciendo, difícilmente alguien de otr planeta comprender y responder el mensaje. "Un mensaje efectivo dirigido a los extraterrestres debería -como mínimo- ser comprensible para todos los humanos.

Utilizar el protocolo METI en pruebas locales nos permitirá mejorar y desarrollar el potencial de nuestros mensajes,” agregan.

Está claro que las posibilidades de encontrar vida inteligente en algún rincón del universo han aumentado en los últimos tiempos. Hace mucho que se especula con la existencia de muchos sistemas estelares como el nuestro, pero en los últimos años se ha comprobado realmente que están allí, y cada semana se descubre algún nuevo exoplaneta. No es mala idea comenzar a revisar la forma en que podemos comunicarnos con ET: cada día estamos más cerca de encontrarlo. (ABC)

          An Earth-like Atmosphere May Not Survive Proxima b's Orbit        
Proxima b, an Earth-size planet right outside our solar system in the habitable zone of its star, may not be able to keep a grip on its atmosphere, leaving the surface exposed to harmful stellar radiation and reducing its potential for habitability. At only four light-years away, Proxima b is our closest known extra-solar neighbor. However, due to the fact that it hasn't been seen crossing in front of its host star, the exoplanet eludes the usual method for learning about its atmosphere...

          A nearby Sun-like star hosts four Earth-sized planets        

Exoplanet discoveries are getting pretty common, so it takes something special to catch our attention. A star called Tau Ceti fits the bill, as it's just 12 light years away and unlike the Trappist-1 red dwarf, is very similar to our own yellow dwarf (G-type) sun. Researchers have determined that it probably hosts planets like Earth that sit in its habitable zone. The only hitch is that the star is known to have a massive debris disk that probably bombards its worlds with asteroids, so living there would be a pretty big challenge.

Four rocky worlds were found, with two in the habitable zone, about 0.5 and 1.25 times as far from their star as the Earth is from the Sun. That works out well, as Tau Ceti is a bit smaller (78 percent) than the Sun, and is correspondingly less intense. The smallest of the worlds is about 1.7 times the size of Earth, but the habitable zone planets are much larger "super Earths" that could potentially support life.

However, Tau Ceti is known to have a big debris disk that probably produces far more impact events via comets and asteroids than we have on Earth. While that makes life improbable, the discovery is still important because of the techniques used.

On smaller stars, planets can be detected by the "transit method," observing the dimming of light as planets pass in front. That doesn't work as well for bigger stars like Tau Ceti though, as the light levels drown out any dimming.

The W.M. Keck HIRES-MAGIQ detector

Instead, the team observed wobbles in the star's movement as small as 30 centimeters (one foot) per second. That has only become possible recently by combining multiple observations from different instruments and sophisticated modeling. In this case, the team obtained observations from the HARPS spectrograph on the European Southern Observatory in Chile, and Keck HIRES (above) on the W.M. Keck Observatory in Mauna Kea, Hawaii.

"We can [now] disentangle the noise due to stellar surface activity from the very tiny signals generated by the gravitational tugs from Earth-sized orbiting planets," said UC Santa Cruz Professor and co-author Steven Vogt. "Our detection of such weak wobbles is a milestone in the search for Earth analogs."

Using the new techniques, the same team actually ruled out two planets they previously identified in 2013 as planets. "But no matter how we look at the star, there seem to be at least four rocky planets orbiting it," said coauthor Mikko Tuomi.

We can disentangle the noise due to stellar surface activity from the very tiny signals generated by the gravitational tugs from Earth-sized orbiting planets. Our detection of such weak wobbles is a milestone in the search for Earth analogs.

The team hopes to refine the techniques to find wobbles as small as 10 cm (4 inches) per second, small enough to detect Earth-sized planets. That could be crucial, because while its easier to spot exoplanets around dim red dwarf stars like Trappist-1 using the transit method, astronomers are beginning to wonder if such stars can actually support life.

Planets tend to get tidally locked to red dwarf stars early in their life because their years are so short -- often a week or less. As a result, much like our moon is to the Earth, one side is constantly exposed to radiation and the other is in the dark. "Because of the onslaught by the star's radiation, our results suggest the atmosphere on planets in the Trappist-1 system would largely be destroyed," said researcher Avi Loeb.

That makes the likelihood of life just one percent compared to Earth. Since life has enough challenges already, it's probably got a much better shot on a planet around a type-G, main sequence star. We know for a fact that those can support life, as here we are.

Drtivá větÅ¡ina exoplanet byla objevena nepřímými metody. Jen hrstku vidíme přímo, ale má to háček. Jedná se o obří světy, které jsou mladé, horké a dál od svých hvězd. Planety jsou přezářeny světlem svých hvězd a jsou samozřejmě také mnohem menší. Jednou z metod, jak planety pozorovat přímo, je využití clony, která světlo hvězdy zablokuje. […]

V roce 1960 u Tau Ceti a Epsilon Eridani hledal Frank Drake v Green Bank jako vůbec první člověk signál mimozemských civilizací. Svým projektem Ozma tehdy položil základny SETI. Nyní astronomové hlásí objev několika planet […]

Pokud ji znáte, můžete diskutovat o možných složeních planety. K vypočtení hustoty potřebujete hmotnost, kterou získáte měřením radiálních rychlostí a poloměr dodaný pozorováním tranzitů.

          Los grandes observatorios que vienen: el GMT        
Después de ver un poco por encima las características del gigantesco E-ELT que se está construyendo en Chile, veamos otro de los gigantes que en unos años estará operativo: el GMT, o Giant Magellan Telescope.

Aún sin llegar a las colosales dimensiones del E-ELT (con sus casi 40 metros de diámetro de espejo principal), el GMT contará con 7 espejos de 8'4 metros de diámetro cada uno. Este diámetro es el máximo que se puede alcanzar con un único espejo, ya que si fuera mayor se deformaría y se rompería al moverse; cada espejo tendrá un peso de entre 15 y 16'5 toneladas. La distribución que tendrán estos 7 espejos equivalen a un telescopio con un diámetro de 24'5 metros, con una superficie colectora de unos 368 m2, que no es poca cosa. La estructura del telescopio pesará unas 1100 toneladas y la cúpula alcanzará los 68 m de altura.

A pesar de estar construyéndose también en Chile, este telescopio no pertenece al European Southern Observatory, sino a un consorcio internacional formado por diversas universidades y centros de investigación de EEUU, Australia, Corea del Sur y Brasil.

En esta ESPECTACULAR fotografía se aprecia con claridad la luz zodiacal y la excelente calidad del cielo del lugar donde se ubicará el GMT. Créditos: Yuri Beletski, Las Campanas Observatory.

El GMT estará enfocado a estudiar la formación de estrellas y sistemas planetarios, propiedades de los exoplanetas, poblaciones estelares y la evolución de su química, formación y evolución de galaxias, estudio de la materia oscura y la energía oscura... Hay mucha más información de los objetivos científicos de este nuevo observatorio en su Science Book.

Los láseres excitan los átomos de sodio en las capas superiores de la atmósfera, creando así una estrella artificial. El sistema de óptica adaptativa analizará cómo esta estrella se ve perturbada por la atmósfera y enviará instrucciones al telescopio para que, moviendo los espejos a alta velocidad, anular esta perturbación y obtener así imágenes más nítidas.

NASA's Jet Propulsion Laboratory has released a trio of faux travel posters for several "exoplanets" — planets outside our own solar system, orbiting different stars. The posters were produced under JPL's "PlanetQuest" banner, which they call "the search for another Earth." So far, PlanetQuest has discovered 4,988 exoplanets.

As Engadget notes, the posters are echoes of the Works Progress Administration's travel prints from the mid-1930s; they also probably remind Disney-goers of the travel posters on the walkways leading to the Star Tours ride. The images represent both something old and something entirely new on the frontiers of human exploration.

Click on the posters to expand them to full high-resolution size.

Kepler-16b

The poster for Kepler-16b draws attention to its two suns, as it orbits a pair of stars. NASA itself points out a science fiction planet that fits the same description: Luke Skywalker's Tatooine from "Star Wars." NASA also notes that, while it's depicted in the poster as being a more Earth-like, terrestrial planet, it may also be a Saturn-like gas giant. Also, chances for life there aren't great — the temperature is close to that of dry ice. Still, that two-sun sunset could actually be real.

HD 40307g

HD 40307g is somewhere between being a big Earth and a mini-Neptune, according to NASA, coming in at almost eight times the Earth's mass and bringing with that far greater gravity. Scientists remain unsure if it's got a rocky surface, or if the surface is buried between thick layers of gas and ice — perhaps a bit like one of the worlds from "Interstellar."

Kepler-186f

This is the first planet the size of Earth discovered in a potentially "habitable zone" orbiting other star, according to NASA — which means its surface has the potential for liquid water. It's got a cooler, redder sun that Earth's (you know, like the one from Superman's home planet of Krypton). NASA also notes that if Kepler-186f has plant life, the red sun version of photosynthesis, with red-wavelength photos, could make their plant life an entirely different color than the green landscapes of Earth.

          Alert Notice 370: GJ 436 Extrasolar Planet Transit Campaign        

February 12, 2008

REQUEST FOR OBSERVATIONS OF EXTRASOLAR PLANET SYSTEM GJ 436
------------------------------------------------------------------
1. BACKGROUND

Observations of the extrasolar planetary system around GJ 436 are requested to help explain anomalous changes in the transiting properties of a "hot Neptune" type planet (GJ 436b). These perturbations manifest themselves in changes in the larger planet's transit properties. Specifically, the transit time, duration and amplitude may be affected. So far, only transit timing variations (changes in the transit  midpoint) may have been detected.

A recent paper published to ArXiv by Ribas, Font-Ribera and Beaulieu suggests that a previously undetected 5-Earth mass planet may exist elsewhere in the GJ 436 system and that its gravity may be the cause of the anomalies. If the smaller planet does exist, it would be the smallest planet yet detected in a solar system around a main sequence star.

However, that is still a big *if* as there are possibly other astrophysical explanations as well. The theory is provocative enough that it should be checked. The key will be to get large amounts of quality data to confirm or negate this dual planet hypothesis.

This system is not as bright (V=~10.7) and the expected transit length (~1h) is not as long as other extrasolar transit campaigns we have conducted. So this may be a good entry point for those who have not participated in an extrasolar planet campaign before. However, the transit depth is still very low (<.01 mag) so it will be a challenging system. Please follow our photometric guidelines (below) carefully and take your time when reducing the photometry.

Dr. Greg Laughlin (transitsearch.org and University of California, Santa Cruz) has analyzed recent data and measurements from both observers and the literature to come up with the following transit period and ephemeris:

 P = 2.643901 days
T_mid = 2454222.6157 HJD (02:46:36.48 UT May 2, 2007)

Dr. Laughlin has agreed to list anyone who contributes quality data of a transit as a co-author of any paper that may result from this campaign.

2. OBSERVATIONS

Photometric observations of future transits of the system are requested. 

The next transit is scheduled for February 14, 2008 from 06:49-07:47 UT. The actual transit may occur 10 to 15 minutes later. Transits occur about every 2.64385d. A list of subsequent transit dates can be found here:

http://207.111.201.70/transitsearch/dynamiccontent/GJ436____b.transits.txt

GJ 436 is located at R.A. = 11:42:11.1, Dec. = +26:42:24 (2000). Finder charts can be made using the Variable Star Plotter (http://www.aavso.org/vsp) and using "GJ 436" as the star's "name". Please submit your data to the AAVSO using the same name.

The GJ 436 M3V parent star is very red. As a result, it will be very important to submit your airmass values. They can be computed with our Airmass calculator at http://www.aavso.org/observing/programs/ccd/airmass.shtml .    [broken link]

A spectra of the object from Maness, H. L., Marcy, G. W., Ford, E. B. et al. (2007PASP..119...90M) has been posted at this URL: http://www.aavso.org/gj436_spectra

GJ436 itself has these magnitude and colors:
        V     B-V    V-Rc   Rc-Ic   V-Ic
     10.702  1.489  1.073   1.349   2.462

Note that it is intrinsicly very red, so the spectrum is full of molecular bands, and the star is *much* brighter redwards of V (Ic=8.240). The comparison stars in the field are typically much bluer than the target star (the reddest has V-Ic = 1.08). This is good, in that the comparison stars are unlikely to be variable; it is bad, in that everyone's photometry will be on a different "system" unless transformed, and second-order extinction will be important.

The bottom line is that you are probably better off not transforming your data, but be sure that you submit long time series so that we can detrend the photometry for airmass effects, and offset your results so that your data will be on the same scale as other observers. Luckily, the transits are short so you are likely to cover an entire transit and data from two or more observers will not be necessary to get ingress and egress timings. Don't just observe the hour-long transit; be sure you have a long lead-in and exit segment for our detrending needs.

Your best bet is to observe filtered, and with B as your first preference and V as your second preference. B is less affected by molecular absorption, and the star will be fainter at B. There are two advantages to this. First, being fainter means you can take longer exposures, which will reduce the effect of scintillation. Second, and perhaps more important, there will be a smaller magnitude difference between GJ436 and its nearby comparison stars. This means that an ensemble of these comparison stars will yield better results. V-band is a good second choice, but do not go any redder than this.

With a 0.006 magnitude transit depth, every small error gets magnified. Even at 8 micron (SST) depth is 7.3 +/- 0.3 mmag, with no dependence upon filter (so far). When possible, observe when the transit is expected to occur near meridinal crossing so that airmass changes are minimized. Use large apertures so that centroiding of stars does not cause a measurement error.  Get lots of signal/noise in your flats (1 million electrons per pixel is the minimum you should have, usually from a large stack of flats). Try to keep the field in the same spot on your chip (autoguiding really helps for this project). Use ensemble techniques for the photometry if at all possible. Keep accurate time, and make sure your submitted photometry uses the exposure midpoint for its time. I would suggest binning your data in chunks no larger than 30 seconds elapsed time to get good time resolution on your light curve.

          Observing Campaign: Exoplanet Transit Search for GJ 436        

 

 

June 6, 2007

 

Artist Conception
An artist's illustration of GJ 436b (NASA)

From AAVSO Alert Notice 350:

Dr. Greg Laughlin (UC Santa Cruz/Lick Observatory & Transitsearch.org) has requested help in observing GJ 436 to look for transits of previously detected and undetected extrasolar planets.

A Neptune mass planet was recently discovered transiting this M2V class star with a photometric depth of 0.6% and a period of 2.64 days. This is the planet which has been mentioned in the popular press recently as a "hot water ice" planet because it likely contains water solidified by atmospheric pressure.

According to Dr. Laughlin: "The radial velocity data set for the star indicates that the transiting planet has a significant eccentricity. Given the fact that it has a Neptune-like composition, the tidal circularization timescale is quite short, and the presence of an eccentric orbit thus strongly indicates the presence of additional planets in the system. These can potentially be detected through transit, or alternately, and more provocatively through precise timing of the transits of the known transiting planet.

"This is probably the most important opportunity that has come around for small-telescope observers in a long time."

Charts & Additional Info:

Photometry Guidelines

Since we are looking for extremely small transit depths, please use ensemble techniques if your software permits. Use the set of 8 comparison stars for the field as your ensemble.

If you use the standard comparison and check scheme, the best stars look like two stars in the grouping just NNW of the target:

                                  V      V-B   V-Rc   Rc-Ic  V-Ic
comp   11:42:28.04 +26:49:42.6  10.684  0.986  0.582  0.506  1.082
check  11:42:12.08 +26:46:07.4  11.370  1.071  0.562  0.503  1.060  

These are about as close in color as possible to the target, but there will still be systematic differences between observers if data is not transformed. Beware that the 11.370 star has a fainter companion about 15arcsec to the NW - try to use an aperture small enough to exclude this companion.

GJ436 is near 11th magnitude, so exposures will be relatively long in comparison to some of the other transiting targets. Scintillation will not be as important. If you can do two filters, it is strongly advised to do so in order that your data can be transformed. Choosing B and V would be your best choice, as B is less influenced by molecular lines and, since GJ436 is fainter in the blue, will enable longer exposures so that scintillation is even less important. Remember that exoplanet transits are 'grey', meaning there is little advantage for any specific bandpass in maximizing transit depth. Instead, use filters to: standardize your observations; cut down the amount of light so that you can use longer exposures; and to remove the influence of spectral features like molecular absorption lines that will plague unfiltered measurements.

We will provide instructions as to how to determine your transformation coefficients in the near future.

          Photometry for Astronomers        

Photometric results of VAO Observations on 11/21/2011
Astronomers interested in the variability of stars need a tool to understand how they vary in time.   This tool is called photometry and it is widely used by astronomers to study not only intrinsic star variability but the more familiar exoplanet transit searches.    It is also used to study galaxies and other extended objects.  So why study changes in "brightness"?

Changes in brightness can lead to the discovery of eclipsing binaries, transiting exoplanets, exotrojans and exomoons.   It can tell you about the morphology of Active Galactic Nuclei and about the properties of supernovae explosions.  You can infer from the data when you collect it over time about the physical properties of the object you are studying.

The plots to the right are examples of light curves or in other words many measurements of the intensity of stars over a period of time.  On the horizontal axis you have number of exposures. On this particular case each tick on the axis is roughly 80 seconds.  On the vertical we have the instrumental magnitude of the star.   As you can tell by the graphs there are stars on this ensemble that vary on time scales of hours.  These measurements were taken on VAO in Webster NY and the graphs are the results of the photometric pipeline I setup for this particular field.

Kitt Peak National Observatory

Today there are no pretty pictures of the wonders of the Universe from the VAO observatory in Webster, NY. Instead, I bring you images of where I will be for the next week,  Kitt Peak National Observatory.  Located 56 miles from Tucson, Arizona at an elevation of 6,875 feet above sea level.   KPNO has the largest collection of telescopes in the world. 24 optical telescopes and 2 radio observatories.  

So why KPNO?


On the left, the WIYN 0.9 m Observatory

KPNO houses the WIYN consortium 0.9 meter telescope of which Rochester Institute of Technology is a partner among other educational institutions.   As part of the partnership, faculty and students of RIT  have the opportunity to conduct research and educational projects.   

Why is this important to me, you say? Well to begin, the night sky at KPNO is one of the best in the nation and the opportunity to image with a telescope that is 3 times the aperture size of the one I have is compelling.  Not to mention this will advance 2 of the projects I am currently working on.  The first project is on AGN (Active Galactic Nuclei), galaxies where their central super massive blackhole is accreating mass.  The second project is on the characterization of transiting exoplanets and their apsidal precession due to the effects predicted by Albert Einstein's theory of General Relativity.

Stay tuned for the results of this trip!

          Elohimization : 130 scientists and officials meet to discuss the creation of genomes from scratch        
Last week’s meeting at Harvard of more than 130 scientists, lawyers, entrepreneurs, and government officials, from five continents, to discuss the topic of creating genomes from scratch is probably the most important ‘Raelian news’ of the month.
When Maitreya Rael, founder and spiritual leader of the Raelian Movement, introduced in 1973 the idea that every form of life on earth has been engineered by scientists who created these unique genomes from scratch, most of the scientists dismissed his claim as science fiction. 43 years later, scientists, business individuals and government officials agree to meet and debate about its feasibility, including for the creation of human genomes.

They are not debating about the possibility that our own genome has been engineered from scratch yet, but it should be on everyone’s mind. If we can envision to create a genome from scratch, it should be natural to think that our own genome could have been engineered as well. By whom would be the next question and the obvious answer will be: ‘ by advanced scientists’.

“Where would they come from?” is the next natural question…
43 years ago, scientists were saying that there are millions of stars in the Milky Way but there are no planets. The existence of planets was a mere speculation and no scientist caring for their career would dare to defend the possibility of an infinity of star systems similar to the solar system. 43 years ago, most scientists believed that our existence was the results of billions of positive mutations that lead to our extraordinarily complex ecosystem and the odds to find another such luckily elaborate ecosystem was even slimmer than having one on Earth. The official scientific dogma was that we were probably the only living human beings in the galaxy and probably in the ‘expanding and limited universe’, a very egocentric vision similar to the ones that made us believe in the past that the sun was rotating around the earth. The first planet outside of our solar system was reported in 1997. In 2014, there was an official count of 1,700 planets detected in our galaxy. A few days ago, the Kepler mission reported about 1,284 more planets and Nasa now counts 21 exoplanets that are labelled as ‘habitable’. Stars are not observed as stars only anymore, they are looked at as potential ‘planetary systems’ with potentially habitable planets. The number of scientists who think that habitable could also mean inhabited is growing. There are also a growing number of them who postulate that the universe might be infinite and that the event that is referred to as the Big Bang is actually a local event in an infinite universe where big bangs and new clusters of galaxies are created every day, every second, an infinite number of times. But that is digressing.

The possibility that human beings coming from another planets created us is not science fiction anymore. It is scientifically acceptable to think that life exists in other planets and that some of these living entities are able to design new DNAs and create other forms of lives.

These scientists probably had meetings with entrepreneurs, ethicists, government officials before they created new simple forms of life. Their creations became more elaborate, the ethicists became more alarmed until they decided to have the laboratories transferred in one of the ‘habitable exoplanets’ that they had discovered. They had fun creating diversity in beauty and functions which naturally led them to create another human being in their image.
This account of our past is coherent with the multiple reports of the creation of life on every continent by ‘gods’ who were actually only advanced scientists. The concept of a unique god creator is fairly recent and even the Bible uses a plural term ( Elohim) to refer to the one(s) who created life.
It also explains why all forms of life possess identical pieces in their DNAs as the DNA code is a creating language and the same language was used for all forms of life on earth. Our scientists may elect to use a DNA code that use different bases for their future creation. In doing so, they will use existing pieces of their previous creations and include them in the new ones, not reinventing each time the pieces of codes that they know will bring specific functions. This is how the same pieces of DNA can be found in the apes and in the human being. It doesn’t mean that the apes evolved and experienced millions of mutations until they became an homo sapiens. It is much easier to imagine scientists designing the apes and later designing the human beings, using their accumulated knowledge to improve their creation. The missing links in the evolution theory will always be missed because they were simply not needed.

Life on earth is what we can really call an intelligent design and the designers are the Elohim of the Bible, a civilization that wishes to be welcomed back on Earth.
Our scientists are becoming creators, they are becoming like the Elohim… as Maitreya Rael said when he read about the meeting of scientists and officials at Harvard: “Here is the beginning of the Elohimization”.

One of the tenets of the Raelian philosophy is that life has always existed and will always exist in an infinite universe. In the infinite cycle of life, a meeting of 130 individuals at Harvard was a milestone in the inevitable path where the created become creators. They will succeed, provided that a few of their colleagues do not take decisions that will lead to our destruction before. But that’s also another story.

          Applied Physics/Physics Colloquium        

Optical frequency combs are providing powerful tools for laser spectroscopy. Mode-locked femtosecond lasers and related emerging miniaturized devices can produce a large number of precisely evenly spaced spectral lines. Almost two decades ago, such spectral combs were introduced as tools for optical frequency metrology, motivated by the challenges of precision laser spectroscopy of atomic hydrogen as tests for fundamental physics laws. Current precision spectroscopy of hydrogen with frequency combs focuses on the "proton size puzzle", i.e. the discrepancy between the rms proton charge radius determined from Lamb shift measurements in ordinary hydrogen and in muonic hydrogen. Laser frequency combs provide the long-missing clockwork for optical atomic clocks, which are now approaching relative frequency uncertainties of 10-18. Distant clocks can be compared via optical fiber links at the 10-19 level, opening new opportunities for relativistic geodesy and astronomical interferometry. Frequency combs in space will permit new tests of Einstein's equivalence principle. As calibration tools for astronomical spectrographs, frequency combs are facilitating the search for exoplanets, and they may lead to direct evidence for the accelerating expansion of space in our universe. Laser combs are also enabling novel broadband molecular spectroscopy. They can dramatically improve the resolution and recording speed of Fourier spectrometers, and they are creating intriguing new opportunities for highly multiplexed nonlinear spectroscopy and microscopy.

          Researchers Discover Two 'Super Earths' Just 12 Light Years Away        

A team of scientists have discovered what they believe to be two large Earth-like planets orbiting a star just 12-light-years away.

The team, led by researchers at the University of Hertfordshire, discovered the 'Super Earths' orbiting the Tau Ceti solar system right within the habitable corridor known as the 'goldilocks zone'.

Calling the discovery a "milestone", Dr Fabo Feng, research fellow at the University of Hertfordshire and lead researcher on the study, said: "We're getting tantalisingly close to observing the correct limits required for detecting Earth-like planets."

The scientists were able to analyse the planets around star system by measuring the 'wobble' of the star itself as the planets orbit around it.

Sun-like stars like our own are, for obvious reasons, considered our best hope of finding habitable life throughout the rest of the galaxy.

The hope is that if the two outer planets are found to be rocky and habitable then they could become the first real contenders for colonisation outside of our own solar system.

Tau Ceti is one of our closest neighbours residing just 12 light years away, making it a tempting target for astronomers and scientists.

Of course with every piece of good news comes a word of caution. Little is know about the conditions within Tau Ceti and while both planets have potential there is still every chance that they're inhospitable for external reasons such as constant bombardment from asteroids.

The discovery of these two 'Super Earths' is the result of years of work starting in 2013 when the team first set their gaze upon Tau Ceti.

"We realized that we could see how the star's activity differed at different wavelengths and use that information to separate this activity from signals of planets," said Dr Tuomi, lead researcher back in 2013.

"Since then we've painstakingly improved the sensitivity of our techniques and could rule out two of the signals our team identified in 2013 as planets. But no matter how we look at the star, there seems to be at least four rocky planets orbiting it."


          4 BREATHTAKING SOLAR ECLIPSES YOU CAN SEE FROM OTHER PLANETS

Four Breathtaking Solar Eclipses You Can See From Other Planets
By Maddie Stone,
Gizmodo, 1 August 2017.

On August 21st, millions of Earthlings will gather to watch as a total solar eclipse sweeps across the centerline of the United States over the course of 90 minutes. For many, it’ll be once-in-a-life-time spectacle. But if you had a spacecraft on hand, you wouldn’t need to wait decades for the next total solar eclipse to arrive at a town near you - you could simply jet off to Mars, Jupiter, Saturn, or even Pluto. That’s because there’s a veritable zoo of solar eclipses occurring all across our solar system, all the time.

To be fair, none of these extraterrestrial eclipses is quite like the total solar eclipse here on Earth, where a quirk of celestial geometry causes the Moon to stack perfectly over the Sun, leaving a fiery ring of coronal jets to illuminate the sky. Some satellites, like Mars’ moon Phobos, are too small to engulf the Sun from the perspective of an observer on the planet, resulting in what astronomers call a transit. In other cases, like that of Saturn’s moon Titan, the angular size of the satellite in the sky is far greater than that of the Sun, resulting in a solar occultation. But that’s just the basics - eclipses, it turns out, come in all shapes and sizes, and studying them can tell us a lot about our cosmic neighborhood.

1. Tiny transits at Mars

wpsCDED.tmp

For most other planets, we have to imagine what a solar eclipse would look like from the surface (or, in the case of a gas giant, the cloud-tops). But when it comes to Mars, we’ve actually seen quite a few.

In 2004, NASA’s Spirit and Opportunity rovers captured six solar transits events from the surface of Mars - four involving the potato-shaped moon Phobos, another two starring the even runtier satellite Deimos. They were, according to a paper published in Nature the following year, the first direct images of satellites transiting the Sun from the surface of another planet. (Phobos eclipses had been observed indirectly even earlier, in data collected by NASA’s Viking lander and Soviet-led missions to Mars.)

According to Mark Lemmon, an astronomer at Texas A&M University and co-investigator on the Spirit and Opportunity rovers, early solar eclipse observations helped NASA refine the positions of Mars’ moons in the sky. “Despite observing Phobos and Deimos for 120 years from Earth, they’re small and far away,” Lemmon told Gizmodo. Before NASA’s rovers landed, “the uncertainty about where Phobos would be at any given time was about as big as Phobos.” Once eclipse observations had improved the orbits of the two moons, the European Space Agency’s Mars Express Orbiter was able to point its camera accurately enough to capture high-res images of both, Lemmon said.

Eclipse-watching on Mars has only gotten better, especially since NASA’s Curiosity rover landed in Gale Crater in August 2012. Just look at this footage Curiosity captured in 2013, of 14 mile-wide Phobos racing across the Sun, transforming our beloved star into an eerie cyclops monster over the course of 32 seconds:


“I think that’s the best shot of an eclipse [on Mars] we have,” Lemmon said of the Curiosity video, adding that the rover has continued to make solar eclipse observations since, including the eclipse shown below, which occurred this past May. Even though Spirit and Opportunity refined the positions of Mars’ moons more than a decade ago, there’s still plenty we can learn by watching their transits.

“Even now, while there’s no missing where Phobos and Deimos are, their orbits are changing all the time due to the push and pull of gravity,” from Mars, Lemmon explained. “In particular, Phobos raises a tiny tide on Mars - a slight displacement of the rock surface, which in turn leads to a gravitational pull on Phobos, changing its orbit. That is why Phobos is spiraling in toward Mars and will eventually be destroyed.”

Indeed, eclipses may be critical to figuring out how soon Phobos faces annihilation - and when Deimos will be cast away into deep space.

2. Hazy eclipses at Saturn

wpsBD94.tmp

With 62 confirmed moons, Saturn’s skies offer myriad eclipse-viewing opportunities, from tiny solar transits to massive occultations to moons stacked atop other moons. But of all the gas giant’s many satellites, few produce an eclipse as otherworldly as Titan, a massive methane cauldron that challenges our understanding of the kinds of places life might emerge.

It was the Voyager 1 spacecraft that spotted the first solar occultation at Titan in 1980, according to a paper published in The Astrophysical Journal. As Titan swept across the Sun, Voyager captured some of the light that filtered through its hazy atmosphere, which scientists used to confirm that the moon’s skies are composed mostly of nitrogen. Since NASA’s Cassini probe arrived in orbit around Saturn in 2004, we’ve witnessed many other Titan eclipses, which we’ve used to probe the chemistry of the moon’s thick haze.

Some of what we’ve learned even has implications for understanding planets beyond our solar system.

In 2014, analyzing visible and infrared spectra collected by Cassini during solar occultations, researchers demonstrated that Titan absorbs, refracts, and scatters sunlight in ways that may obscure information about deeper parts of the atmosphere. This, the researchers wrote in a paper published in PNAS, could have ramifications for elucidating the atmospheres of exoplanets, particularly “super Earths.” “Haze has a dramatic effect on the transit spectra,” the researchers wrote, noting that it “substantially impacts the amount of information that can be gleaned.” This information could prove incredibly useful when the James Webb Space Telescope starts peering into the atmospheres of distant planets over the next few years.

But as valuable at the science is, astronomers are mostly drawn to Saturnian eclipses because of their sheer beauty.

“In most cases, we imaged eclipses because they are just wondrous events, at Saturn as they are on Earth,” Cassini imaging lead Carolyn Porco told Gizmodo. “It was part of my desire, from the very beginning of the [Cassini] mission, to turn our image-taking responsibilities at Saturn into a video documentary of everything there was to see there, including celestial motion.”

3. The rare, 42-year eclipse at Uranus

wps27F9.tmp

Solar eclipses are a fairly common for Jupiter and Saturn, but not so for Uranus, a planet which, in flagrant defiance of celestial convention, circles our Sun tipped over on its side, its spin axis almost perfectly aligned with its orbital plane. Because of Uranus’ funky tilt, its poles are alternately illuminated during its 84-year trip around the Sun. The moons, which circle Uranus in the band of rings stretched across the planet’s equator, only align edge-on with the Sun ever 42 years, making solar eclipses a rare event for this lopsided Ice Giant.

Rare, but not impossible to catch. In 2006, just as Uranus was approaching its summer equinox, the Hubble Space Telescope caught a never-before-seen-glimpse of the moon Ariel traversing the face of the ice giant and casting a shadow, or umbra, on the planet’s blue-green cloud tops. From the “surface” of Uranus, it would have looked like a solar eclipse.

wps4A9A.tmp

“These observations were planned only to study the atmosphere of Uranus - the detection of Ariel and its shadow were purely serendipitous,” Heidi Hammel, Executive Vice President of AURA, who helped analyze the image while working at the Space Science Institute, told Gizmodo. “This moon shadow image is more a beauty shot than a science result.”

Lawrence Sromovsky, astronomer at the University of Wisconsin-Madison who also helped analyze the image, noted that Ariel’s shadow creates a region of totality about the same size as the moon itself - a very different situation from what we see during an eclipse on Earth, where the area of total eclipse is fairly small, and surrounded by a much larger region of partial eclipse. This, he explained, is due to the fact that at Uranus, Ariel is roughly ten times bigger in the sky than the distant Sun.

As Uranus continued to approach the summer equinox, there were other eclipses of other large moons, including Umbriel, Titania, and Oberon. But Ariel’s eclipse was the money shot, and it’s likely to stay that way for a while - the next equinox at Uranus won’t be until 2049. Maybe, if we’re lucky, the weird world will have had another visitor by then.

4. Years of solar eclipse at Pluto

wps71C7.tmp
From 1985-1990, Pluto and Charon were constantly eclipsing each other. Image: NASA.

Pluto may seem like a cosmic castaway, taking 248 years to complete a single orbit some 3.7 billion miles from the Sun. Thankfully, it’s got Charon, a moon approximately half its size with which it’s locked in an endless gravitational embrace. And because Charon is so close - just 12,000 miles from Pluto - when eclipse season hits, eclipses happen a lot.

“When Pluto’s in eclipse season, twice during its 248 year orbit, because Pluto and Charon essentially orbit around each other every six days, you get an eclipse every six days,” Planetary Society astronomer Bruce Bettstold Gizmodo. “Of course, they’re tidally locked,” meaning the two bodies never rotate with respect to one another, “so you’d have to be on the Charon-facing side to see it.” But if you were on the right side, you’d see solar eclipses quite regularly, and for years on end.

While regular eclipses would make Pluto terrible for solar farming, they’ve proven damn useful for astronomers. Before the New Horizons spacecraft zipped past Pluto in 2015, some of our best intel on the dwarf planet came from Charon’s incessant photobombing.

“The last eclipse season was not that long ago, and astronomers used the event - Charon in front of Pluto, Pluto in front of Charon - to resolve the two bodies,” Betts said. “They got a better idea of their size, brightness, and color.”

Indeed, the mutual eclipses of Pluto and Charon astronomers observed between 1985 and 1990 led to some of the very first “maps” of Pluto, including the image below, which shows a bright south polar region we now know to be a mixture of nitrogen and methane ice.

wps6133.tmp

For comparison, this is what Pluto looks like today, two years after the New Horizons flyby.

wps7B5.tmp

“The whole thing is pretty amazing,” Betts said, noting that the sunlight is so weak at Pluto astronomers had struggled to get any resolution at all on the icy world. “But the fact that it was so hard to study Pluto is what drove them to do it.”

There are many other incredible eclipses around the solar system we didn’t get into here - take Jupiter, whose four largest moons line up between the Sun and the gas giant with every single rotation due to the planet’s lack of axial tilt. “It never stops having eclipses,” Betts said. Or Neptune’s mysterious moon Despina, which a citizen scientist discovered transiting the sun when he re-analyzed old data from the Voyager 2 flyby in 2009.

Then, there’s the eclipse here on Earth. “In terms of eclipses across Solar System, ours is pretty special,” Noah Petro, a planetary geologist at NASA’s Goddard Spaceflight Center, told Gizmodo. “We have this configuration where the Moon perfectly [overlaps] the Sun, so that we can see the solar atmosphere. And it’s not only the size of our Moon, but the Moon at this point in time - in early lunar history, the Moon was too close.”

So, as you’re making your travel plans to hit the centerline of the eclipse on August 21st, enjoy the fact that what you’re about to see is special. But it’s also more than an Earthly phenomena. It’s a connection to a far grander celestial choreography that promises to dazzle observers for eons to come.

          INFOGRAPHIC: SPACE TELESCOPES OF THE FUTURE        

wps1F19.tmp
It’s been more than 25 years since Hubble Space Telescope was launched into low earth orbit, where it continues to operate alongside the more youthful Kepler Space Observatory to this day. These pioneering space telescopes have provided us vast amounts of information about our solar system and the universe at large, but we are long overdue for an upgrade. Here, in this infographic by Futurism, are four planned telescopes that will knock the galactic socks off Hubble and Kepler.

However, due to the fact that it hasn't been seen crossing in front of its host star, the exoplanet eludes the usual method for learning about its atmosphere. Inst [...]

          Starshade        

Astronomers have discovered dozens of planets in other star systems that are in the “habitable zone” — the distance from the star where temperatures are just right for liquid water — a key ingredient for life. Yet so far, they haven’t actually seen a single one of them. The planets are all so close to their stars that they’re impossible to see through the starlight.

But scientists and engineers are working on a device that could bring some of these planets to light. Called Starshade, it would work in tandem with a space telescope to block a star’s light, allowing its planets to shine through.

The current design looks like a 10-story sunflower with spikes at the ends of its petals. It would be launched to a point in space where the gravity of Earth, Sun, and Moon are balanced.

There, it would be maneuvered to a spot about 25,000 miles from the telescope. The telescope would take aim at a star within a few dozen light-years that’s known to have a planet in the habitable zone. Starshade would line up in front of the star, blocking it from view. The telescope could then take pictures of the planet and measure the composition of its atmosphere, allowing scientists to look for evidence of life.

The concept has been tested on a telescope in Arizona, and the idea of a starshade is ranked highly by scientists. Even if it’s approved, though, it’ll take a decade or longer for this cosmic flower to bloom — and help look for evidence of life in other star systems.

          WFIRST        

Back in 2012, Christmas came a little early for NASA. In June, the National Reconnaissance Office gave the agency two space telescopes, each with a main mirror as big as that on Hubble Space Telescope. It took some time for the space agency to figure out what to do with the telescopes. But this year, it’s finalizing plans for one of them: It’ll study dark energy, the earliest galaxies, and planets in other star systems.

The mission is known as WFIRST — the Wide-Field InfraRed Space Telescope. It’ll take advantage of the fact that the would-be spy telescope has a much wider field of view than Hubble, allowing it to see an area of sky a hundred times larger.

With that expansive view, WFIRST will look at a billion galaxies across the cosmos. Precise measurements of the location and motion of these galaxies will allow astronomers to measure changes in dark energy over the eons. Dark energy is causing the universe to expand faster as it ages, but so far, it’s not certain what dark energy really is.

The telescope also will look at galaxies in the very early universe to learn more about the birth of the first stars.

And WFIRST will carry a special instrument to block out the light of a star. That will allow the telescope to probe the space around a star for planets — and even to take pictures of the planets.

Scientists and engineers are looking at another way to use WFIRST to take pictures of planets, and we’ll talk about that tomorrow.

Unwrapping a Christmas present

          'ANALOGUE CAELESTIS: BIRTH OF A PARALLEL SPACE AGE' - January 4, 2017        
Beyond the political analysis of the films which recently has been mistakenly said to be biased against Trump, and the blatant parallels of the good guys fighting space Nazis, I discovered that if you look carefully at the films, you may just see an analog planetary system that may look familiar to those who have been following the announcements last year of exoplanets which could sustain life. We know that exoplanet research is in its infancy but by some estimates there are 700 quintillion terrestrial like or Earth-like planets in the universe. I don’t think we can envision what a million or a billion looks like let alone a quintillion and about 600 more quintillion added to that. With those estimated terrestrial planets, I don’t see how anyone can say there is absolutely no way there could be other life in space.

          Science in 2012 – A Review        


“As a layman, I would now say, ‘I think we have it.’ Do you agree?”

These were the words of Rolf-Dieter Heuer, director-general of the particle physics laboratory CERN in Switzerland, on July 4th 2012, and officially announced the discovery of the long-sought Higgs Boson particle. But while evidence for the existence of the ‘God particle’ may have been the breakthrough of the year (if not the decade), there have been plenty of science stories grabbing headlines, both for innovation and controversy. Read on for a reminder of the stories you saw, and a few that may have slipped past you as well.

Physical Sciences
The discovery of the Higgs Boson particle has not been easy – it took months of gathering data from over 500 trillion particle collisions at the Large Hadron Collider (LHC) at CERN. The staggering amount of data collected finally allowed the researchers to confidently claim that the new boson they had found, with a mass of 125 gigaelectronvolts, was indeed the elusive Higgs Boson, as predicted by theorist Peter Higgs almost 50 years ago. The existence of this particle is crucial to the Standard Model of physics – although somewhat unfortunately no other particles have yet been discovered. Baby steps, I suppose.

Sometimes, though, the understanding of our world, solar system and universe just cannot be achieved with a particle accelerator; sometimes you need a hovering sky crane gently lowering a rover in the middle of a crater. Only NASA could have achieved a feat such as this, and in August the first low-resolution images from the Curiosity rover were received from Mars. While no signs of life have yet been confirmed, soil samples analysed by Curiosity reveal a surprisingly close composition to that of Hawaii. Further afield, more and more exoplanets are being discovered, with the closest one yet a mere 4.4 light years away orbiting Alpha Centauri, while another exoplanet 40 light years away is believed to be made entirely of diamond.

Despite these successes, NASA’s monetary support from the US government continues to dwindle, even resulting in NASA holding a cake sale to highlight this. Their lack of funds may pave the way for more commercial enterprises – this year saw SpaceX’s Dragon spacecraft rendezvous with the International Space Station, and of course Red Bull made Felix Baumgartner’s ascent (and rather more rapid descent) to the stratosphere possible.

Life Sciences
CERN was not the only organisation to acquire large amounts of data this year – the Encyclopedia of DNA Elements (ENCODE) project collected 15 terabytes of data over 5 years in order to characterise all of the ‘functional’ parts of the human genome. They predict that at least 20% of the genome is involved in regulating gene expression – with genes for proteins themselves making up just 1% of the total DNA. Another ambitious project was the start of mapping the wiring of the mouse brain, a project which complements the Human Connectome project also currently underway. With mouse models being common throughout neuroscience, understanding the similarities and differences between human and mouse brains will be invaluable in elucidating the mechanisms behind conditions such as Alzheimer’s disease and schizophrenia. In medical science, stem cells continue to show their potential in treatment with the (controversial) discovery of stem cells in women’s ovaries which are capable of producing new eggs; this alongside the creation of egg cells from stem cells in mice by Japanese scientists in October. A powerful new painkilling substance with fewer side effects than morphine has potentially been found in a truly unexpected place – the venom of the Black Mamba snake. It appears to work by a different mechanism to conventional painkillers, although in its current form (being transmitted along with incredibly potent neurotoxins when bitten by one of the deadliest snakes in Africa), it probably isn’t quite ready for mass release.

The death of Lonesome George, the last known individual of the Pinta Island tortoise subspecies and symbol of the Galapagos Island conservation effort, occurred in June. But as extinction occurs, so too does the discovery of new species, with two of the world’s smallest vertebrates being found this year – Paedophryne amanuensis, a frog of just 7mm from Papua New Guinea, and Brookesia micra, a dwarf chameleon from Madagascar (juvenile pictured).
 

And, of course, no life sciences review would be complete without mentioning at least one GM story. University of Wyoming scientists genetically engineered silkworms to produce large amounts of spidersilk, which has higher tensile strength than that of steel. Future applications may include sutures and body armour.

Out of the Lab
While this year may have seen some major scientific advances, controversy has never been far behind. A paper describing mutations to an H5N1 avian flu strain so that it was able to infect ferrets by air was initially only allowed to be published if certain details were left out. Only 5 mutations were required, and the US National Science Advisory Board for Biosecurity (NSABB) was concerned that the information could be dangerous in terrorist hands. Eventually, the paper was published some months later.

At the same time, there has been a huge push for more transparency and open access to peer reviewed work. A key spark in this explosion was the boycott of Elsevier, Dutch publishing giants who critics claim charge too much for their papers, and are opposed to open access. While the campaign may have seen scientists stepping up to be heard, another story this year may cause the reverse – in October, 7 men were convicted of manslaughter for providing falsely reassuring statements before a major earthquake hit the area around L’Aquila, resulting in over 300 deaths.


So there you have it – 2012, a year dominated by Olympic sport, has come to an end, and with it a year of discoveries, inventions and exploration. If there is one concept and, in the case of 2012, one headline-grabbing event, to sum up some of the biggest breakthroughs of the year, and to sum up science in general, it must surely be: Curiosity. Here’s looking forward to 2013.

          Ø¯Ø§ØºØªØ±ÛŒÙ† سیاره جهان کشف شد !        
براساس گزارش نیچر،‌ این سیاره در مدار ستاره‌ای به نام  KELT-9 در فاصله 650 سال نوری از زمین در گردش است. این اولین‌باری است که اخترشناسان موفق به ردیابی سیاره‌ای در نزدیکی ستاره‌ای اینچنین داغ شده‌اند.
دمای سطح سیاره KELT-9b به شکلی جنون‌آمیز داغ است و در طول روز به 4326 درجه سانتیگراد می‌رسد. برای مقایسه بهتر است بدانید که دمای خورشید 5526 درجه است و سیاره عطارد که نزدیک‌ترین سیاره به خورشید است در طول روز دمایی برابر 426 درجه سانتیگراد دارد.
دلیل این حرارت شدید فاصله بسیار کم سیاره تا ستاره میزبانش است،‌ستاره‌ای که خود در میان داغ‌ترین ستاره‌های جهان هستی قرار دارد و دمای سطح آن می‌تواند به بیش از 9800 درجه سانتیگراد برسد. به گفته محققان دانشگاه کوئینزلند، دمای این ستاره از 80 درصد از تمامی ستاره‌های شناخته شده در جهان بیشتر است.
به عنوان یک سیاره گازی، سیاره KELT-9b دقیقا 2.8 برابر بزرگتر از سیاره مشتری است، اما تنها نیمی از تراکم آن را دارد و اتمسفر آن نیز به صورت دائم توسط ستاره میزبان به میان فضا فوران می‌کند. درواقع این سیاره به اندازه‌ای داغ است که موجودیت آن موجب شگفتی دانشمندان شده‌است زیرا معمولا شدت تشعشعات و نیروی ستاره‌هایی این چنین عظیم و داغ به اندازه‌ای بالاست که تمامی مواد موجود در اطراف آنها نابود می‌شوند.
@persiancosmology
دانشمندان تخمین می‌زنند به دلیل شرایط دشوار و غیرقابل تصوری که سطح ستاره میزبان دارد،‌این سیاره جدید زندگی دشوار و کوتاه و بی‌رحمانه‌ای دارد و در هر ثانیه 10 میلیون کیلوگرم از جرم خود را از دست می‌دهد. در این صورت تا زمانی که سیاره به کلی نابود شود زمان زیادی باقی نمانده‌است.

Un avion contourne un ovni près de Paris ?

Interrogée par téléphonela témoin me confiera qu’elle a observé le phénomène lumineux, ou l’ovni, pendant 30 minutes environ. Les photos et la vidéo ont été prises depuis la maison avec les fenêtres étaient ouvertes (donc pas derrière une vitre). Plusieurs avions sont passés pendant tout le temps de son observation et un avion aurait même contourné l’ovni (pour l’éviter ?). C’est d’ailleurs ce qui a le plus choqué la témoin. L’ovni semblait près mais la distance réelle était difficile à estimer. En tout cas, il était très bas sur l’horizon (degré d’inclinaison du phénomène : environs 20/25 °). La témoin a vu plusieurs couleurs brillantes qui étaient émises par l’ovni. Elle se souvient d’avoir vu deux formes : un hexagone à gauche et un triangle à droite. L’hexagone était beaucoup plus lumineux que le triangle. Une masse noire semblait se profiler derrière les lumières. Le ciel était dégagé et les étoiles visibles.

Monsieur Fournier me fournira par la suite les informations suivantes :
 Â« En ce qui concerne la taille de l’engin je vous joins deux croquis avec les mesures effectuées ce week-end (ma femme me soutient que c’était juste au-dessus de la maison de la voisine (peut-être à une hauteur de 25/30 m) au bout du champ Â».
« A noter qu’il semble difficile d’admettre que ce soit un appareil militaire, car le Collège Montaigne (700 élèves), se trouve à moins de 100 mètres du lieu de l’observation Â».



Ovnis : Jean-Pierre a recensé les cas les plus troublants dans l’Artois

Cinquante ans que ce Fox Mulder de l’Artois les traque inlassablement à travers le Nord et le Pas-de-Calais, en rejetant les témoignages farfelus, dans un esprit scientifique. Sa quête n’est pas terminée, mais Jean-Pierre D’Hondt a des certitudes. Â« J’ai dénombré 750 cas formels pour le Nord/Pas-de-Calais. Le plus ancien date de l’année 920. Je détaille les 75 cas les plus probants dans mon livre. »

Dans la conversation, Jean-Pierre évoque des cas encore plus troublants, constatés par des pilotes chevronnés, qui n’ont pas intérêt à dire n’importe quoi, sous peine de voir leur licence s’envoler. Â« Les vitesses des engins aperçus sont sidérantes. C’est tellement rapide parfois que le témoin raconte que l’objet se désintègre littéralement avant de réapparaître un peu plus tard. » Un peu ce que raconte d’ailleurs la Cuinchynoise.

On lui pose alors clairement la question qui brûle les lèvres : Â« Vous croyez donc aux extraterrestres ? » Sa réponse est étonnante : nul doute qu’après la lecture de ce chapitre 12, vous ne regarderez plus les étoiles de la même façon.

De plus je reprends tous les cas et les compare avec les listes du GEIPAN afin de lier les deux bases. Le travail a commencé avec la région Nord-Pas de Calais.



Chine: Un O.V.N.I perturbe le trafic aérien dans la province du Sichuan.

L’administration de la ville chinoise de Mianyang, dans la province du Sichuan (sud-ouest) a été contrainte de refuser l’atterrissage à trois avions civils, en raison de l’apparition, dans la zone de l’aéroport, d’un objet volant non identifié, annoncent des médias chinois.
Selon le personnel de l’aéroport, Â« l’objet est apparu dans l’aire de la zone contrôlée par l’aéroport mais n’a pas survolé la piste ».



Un ovni manque de percuter un avion militaire au Chili

Lors d'un show aérien à Puerto Varas (Chili) les spectateurs ont réussi à filmer un ovni qui a failli entrer en collision avec un avion militaire à réaction.
…
Sur les images publiées, on voit un avion militaire chilien monter en flèche dans le ciel. Soudain, un objet semi-sphérique apparaît en se déplaçant dans une direction perpendiculaire à la trajectoire de l'avion. Après avoir failli entrer en collision avec l'appareil militaire, l'ovni disparaît.



Alien Project
Les étranges momies du Pérou

Chers Amis Internautes,
Vous avez été très nombreux, depuis le début de cette incroyable histoire, à me conseiller de lancer une opération de « financement participatif Â» permettant de déterminer, grâce à des analyses scientifiques poussées (principalement ADN et C14), l’origine des corps et des organes momifiés découverts dans le sud du Pérou en janvier 2016.

Nous sommes conscients que des milliers de personnes, à travers le monde, veulent savoir, tout comme nous, s’il s’agit d’une fraude ou d’authentiques reliques biologiques appartenant à des espèces terrestres inconnues ou extérieures à notre planète.

Alors, mon équipe et moi avons décidé, en toute humilité, de vous écouter et de lancer cette opération de crowfunding, baptisée « Alien Project Â», nous permettant d’obtenir les réponses que nous espérons tous.

Grâce à vous, et si vous nous en donnez les moyens, nous allons tirer au clair toute cette affaire. Nous ferons la lumière sur cette histoire et nous vous promettons de tout vous dire.


« Disparitions Mystérieuses : Le cas Dennis Martin » avec Lionel Camy

Chaque année, plusieurs personnes disparaissent dans les parcs nationaux et forêts américaines dans des circonstances mystérieuses.

Lionel Camy, romancier et grand voyageur passionné d'énigmes, est l'auteur du livre "Disparus dans la nature", un recueil d'histoires vraies de disparitions étranges.

Il nous rejoint sur Nuréa TV pour nous narrer le récit de la disparition mystérieuse de Dennis Martin, un enfant de 6 ans qui s'est "évaporé" dans des circonstances énigmatiques en 1969 dans les Great Smoky Mountains.

Il décryptera ensuite cette affaire pour nous et passera en revue les hypothèses (quelles soient rationnelles ou relevant du paranormal) pouvant expliquer la disparition mystérieuse de Dennis Martin, afin que chacun puisse se forger sa propre opinion.


Les réflexions de Churchill sur la vie extraterrestre dévoilées

Suite à l’exhumation d’un essai de Winston Churchill, le public a pu voir le héros de l’histoire britannique sous un angle très inattendu: l’homme au cylindre s’intéressait sérieusement à la vie extraterrestre…

Partant de l'idée selon laquelle il est peu probable que la vie n'existe que sur Terre étant donné l'immensité de l'Univers… Il définit ensuite ce que l'on nomme aujourd'hui la « zone habitable », la zone autour d'une étoile où une planète possède une température compatible avec la présence d'eau à l'état liquide, élément indispensable à la vie. Il précise que la vie ne peut exister que dans des régions où les températures oscillent « à peu près entre le point de congélation et celui d'ébullition de l'eau ».

Churchill ajoute qu'un grand nombre de planètes extrasolaires peuvent sûrement avoir « la bonne taille pour permettre la présence d'eau liquide à leur surface et avoir une atmosphère ou quelque chose de ressemblant ». Selon lui, certaines sont « à la bonne distance de leur soleil pour maintenir une température convenable. »

« Je ne suis pas suffisamment impressionné par le succès de notre civilisation pour penser que la Terre est le seul endroit qui accueillerait la vie, des créatures intelligentes dans cette immense Univers ou que nous serions les êtres les plus avancés physiquement et mentalement », écrit Churchill.


Shape-shifting UFO reportedly deadens sound around witness

An Idaho witness at Idaho Falls reported watching and photographing a fire-colored, shape-shifting object that seemed to silence natural sounds in the area when it passed over, according to testimony in Case 81932 from the Mutual UFO Network (MUFON) witness reporting database.

The witness went outside and was informed by the nephews that the object could be seen in the northwest sky.
“I saw the object when it was leaving. It had a very intense red and orange color to it – very bright. My nephew was the one who took the images. He told me the object, before passing over the house,that it remained a sphere shape, but once it passed over the house it started to change shape. He said, ‘The closest thing that this can resemble is one of those light sabers from that movie “StarWars.”’ It had that same effect. It would stretch. It would go from a sphere to a cigar shape and once it passed the house it went back to just being a sphere. He said all around the object there was this wave-like pattern of fire.”


ALIEN LIFE BOOST: 2017 could be the year we FINALLY confirm ET existence, say experts

Doctor Simon Foster, a physicist from Imperial College London, told Express.co.uk: “In the past, when we thought we had discovered aliens previously, it was a new form of star called the pulsar. 
"We don’t know hardly anything and when we come up against something we don’t know or doesn’t fit into out current understanding, it is quite nice to say that it could be aliens, whereas a lot of it is just a phenomena that we haven’t discovered.
“Either way there is a breakthrough just around the corner.”
…
Cassini, the probe currently studying Saturn and its moons, is the most likely to yield results, says Dr Foster.
The physicist explained that with the Cassini mission set to end next September, it could lead to a startling discovery.


NASA Telescope Reveals Largest Batch of Earth-Size, Habitable-Zone Planets Around Single Star

NASA's Spitzer Space Telescope has revealed the first known system of seven Earth-size planets around a single star. Three of these planets are firmly located in the habitable zone, the area around the parent star where a rocky planet is most likely to have liquid water.

The discovery sets a new record for greatest number of habitable-zone planets found around a single star outside our solar system. All of these seven planets could have liquid water – key to life as we know it – under the right atmospheric conditions, but the chances are highest with the three in the habitable zone.

“This discovery could be a significant piece in the puzzle of finding habitable environments, places that are conducive to life,” said Thomas Zurbuchen, associate administrator of the agency’s Science Mission Directorate in Washington. “Answering the question ‘are we alone’ is a top science priority and finding so many planets like these for the first time in the habitable zone is a remarkable step forward toward that goal.”
At about 40 light-years (235 trillion miles) from Earth, the system of planets is relatively close to us, in the constellation Aquarius. Because they are located outside of our solar system, these planets are scientifically known as exoplanets.


Responding to aliens is a really, really bad idea - Stephen Hawking

Stephen Hawking has advised us earthlings to be extremely wary about answering any signals from aliens when they eventually come calling.
Hawking made the comments during his new online show â€˜Stephen Hawking’s Favourite Places’. In the programme, the renowned astrophysicist ‘visits’ the potentially habitable Gliese 832c, a planet located some 16 light-years from Earth.
“As I grow older I am more convinced than ever that we are not alone,” says Hawking.

Hawking believes there could very well be life on Gliese, but imagines a meeting between the two civilizations as something that would resemble Christopher Columbus meeting Native Americans, saying, â€œthat didn't turn out so well.”
"One day we might receive a signal from a planet like this, but we should be wary of answering back,” he cautions.


The Mysterious Object Which Will Pass Earth in 2017 – Scientists Left Confused

A mysterious unknown object, that many researchers claim is an ‘alien probe’, is set to fly past Earth in 2017. The strange object which is now known as 1991 VG, was first spotted way back in November 1991 by astronomer James Scotti at the University of Arizona.
…
When Scotti first spotted this mysterious strange object which is now called 1991 VG, it was about 10 metres in diameter, passing 280,000 miles from Earth – around 50,000 miles further than the Earth and the moon.

This strange object showed an unusual rapid rate of rotation and its brightness appeared to fluctuate. This behaviour, has not ever been seen before from any asteroid of its size – This mysterious object also had an orbit that was strikingly similar to that of Earth.

Once data was gathered on 1991 VG, Scotti realised this was the second time the unidentified object had passed Earth. The first was March of 1975.

Perhaps this strange object IS in fact an Alien probe sent from the darkest reaches of space!?


UFO sightings hit all-time high, report says

UFOs are visiting at all-time highs, according to new statistics, which say that sightings are most common in the U.S.
The findings are based on data crunched by Sam Monfort, a doctoral student in Human Factors and Applied Cognition at George Mason University. Monfort wrote up his findings in a blog update that used information from the National UFO Reporting Center (NUFORC), an organization that documents UFO sightings.
…
The first recorded flyby occurred in Portland in 1905, where viewers reported seeing a “buzzing” sphere-shaped UFO that descended from the heavens. But sightings have spiked dramatically over the past 30-plus years, with the reported number jumping from around 5,000 in 1980, to roughly 45,000 in 2010.

Le quartier de Conflans survolé par un Ovni ?

Un phénomène paranormal a-t-il eu lieu à Conflans-Sainte-Honorine ? Un couple de la ville dit avoir vu d’importantes formes géométriques lumineuses au-dessus de son quartier. Ce week-end Michel et Isabelle ont distribué des affichettes dans les boîtes aux lettres de leurs voisins afin de recueillir des témoignages.
Photos et vidéo à l’appui, il s’agit selon eux d’un objet volant non identifié (Ovni). Les images sont étranges : on y voit clairement un triangle et un hexagone. Ces formes sont déterminées par des points blancs, rouges voire verts qui scintillent eti s’animent. « C’était vraiment proche des maisons, raconte Michel. Cela fait bizarre d’apercevoir ce genre de chose, je n’en ai pas dormi pendant plusieurs jours ».

Un appel à témoins dans le quartier
Depuis que le couple a vécu ce phénomène, dans la nuit du 29 au 30 novembre dernier entre 0 h 20 et 0 h 50, Michel multiplie les démarches pour en savoir plus. ..



« Les Mystérieuses Reliques du Pérou » avec Thierry Jamin

Thierry Jamin est un archéologue, chercheur et explorateur français, président de l'Institut Inkari Cusco. Il est diplômé en Histoire & Géographie aux Universités françaises de Tours et de Toulouse. Depuis 1998, il consacre ses recherches dans le sud du Pérou à l’étude de la présence permanente des Incas en forêt amazonienne.

Nous aborderons dans cette émission un sujet d’actualité captivant : la découverte récente de reliques très étranges dans la zone désertique Paracas-Nazca du Pérou. Ces reliques ou « créatures momifiées », découvertes dans le désert péruvien en janvier 2016, sont en cours d’analyse (test ADN, C14, …).

Cette découverte archéologique extraordinaire pourrait non seulement bouleverser l'Histoire de l'Humanité mais aussi apporter un éclairage nouveau sur la place de l'Homme dans un univers où il n'est certainement pas si seul que l’on veut bien le croire.




«ABDUCTIONS » avec Nicolas Dumont

Après une formation classique de psychologue clinicien, il s’est formé dès la sortie de l’université à l’hypnose éricksonnienne, puis a exploré les EMC sous quatre angles : en tant qu’expérienceur d’EMC induits, en tant que thérapeute pratiquant une large gamme d’états modifiés de conscience (hypnose, respiration holotropique, chamanisme, méditation, etc.), en tant que psychologue théoricien des EMC et enfin en tant qu’accompagnateur de personnes vivant des expériences extraordinaires de tous ordres.
…
Progressivement, par synchronicités successives, son attention s’est dirigée sur les abductions.

Cette émission sera consacrée en partie à l’histoire de Sonia ,un cas troublant et émouvant d’abductions répétées.



La CIA publie des documents secrets sur les OVNI, et il y a des photos !

La CIA vient de déclassifier et quelques 930.000 documents secrets datant de sa création à aujourd’hui et a rendu le tout accessible avec un moteur de recherche dédié. Parmi ces documents, on trouve des photographies de soucoupes volantes, ou plus précisément d’OVNI, et des détails sur le projet d’expériences psychiques nommés « Stargate Â» entre autres perles.
…
Alors en 2014, une association américaine, Muckroach, a trainé l’agence de renseignement américaine en justice pour que celle-ci publie enfin ses « x-files Â». L’association a eu le soutien de la NSA et d’un journaliste qui souhaitait lui aussi obtenir une copie de ces documents, Michael Best. Et cette année, victoire : l’agence les a enfin mis en ligne, et on peut librement les consulter avec un moteur de recherche dédié.

En tout ce sont plus de 12 millions de pages qui sont disponibles. N’espérez cependant pas y trouver de vrais secrets d’Etat : les documents ont été dument relus et expurgés de contenu trop sensible. Alors on y trouve pêle-mêle des observations d’OVNI supposés avec des photos de piètre qualité, des documents au sujet d’un tunnel secret entre Berlin Est et Ouest construit par la CIA durant la guerre, et un mystérieux programme Star Gate entre autres perles.



Un cosmonaute, témoin d’ovni, vient de décéder

Igor Volk, pilote-cosmonaute et héros de l'Union soviétique depuis 1984, est décédé à l'âge de 80 ans le 3 janvier 2017.
…
En 1985, six membres d’équipage étaient présents à bord de la station spatiale soviétique Salyut-7 : Les cosmonautes Leonid Kizim, Oleg Atkov, Vladimir Soloviev, Svetlana Savitskaya, Igor Volk et Vladimir Jannibekov auraient observé un étrange nuage de gaz orange enveloppant la station. Un éclair de lumière vive aurait aveuglé tous les cosmonautes à bord pendant un certain temps avant de distinguer sept silhouettes à l’extérieur de la station.
…
Rappelons que le cosmonaute russe Vladimir Kovalyonok a révélé dans une émission de télévision intitulée "Rossiya Russian" avoir observé le 5 mai 1981 un étrange objet lumineux depuis la station spatiale Saliout 6.

« Nous étions au-dessus de l'objet qui bougeait parallèlement à notre position puis nous vîmes deux explosions ». Ils ont même demandé à Victor Savinyj d'aller chercher la caméra.

Il déclare que l'objet avait la forme d'un melon et qu'il est très difficile dans le cosmos de déterminer la distance.



Pour qui sont ces OVNIs qui surfent sur nos têtes ?

L’homo sapiens sapiens que nous sommes censés être répondra bien évidemment : « c’est pour nous ! », ou pire: « c’est pour MOI », tant notre anthropocentrisme tous azimuts, nous interdit d’envisager que ce phénomène puisse être destiné à « quelqu’un » d’autre !
C’est aussi vouloir ignorer la quasi-certitude d’existence d’exobiologie(s)dans d’autres galaxies ou parmi les « quelques »10 (exp500) autres univers que le nôtre.

On peut donc légitimement concevoir que l’apparence d’extrême absurdité (à nos yeux) des manifestations ovniennes soit « simplement due à un degré d’étrangeté, élevé, tel que je l’ai proposé dans mon livre et dans un article publié sur le site de l’Académie d’Ufologie.
…
Toutes les voies sont « bonnes », étant donnée l’immensité de notre ignorance en la matière. Le scénario proposé s’inscrit totalement dans mon HYPOTHESE EXTRATERRESTRE GENERALISEE et en constitue une extension logiquement obligatoire.

Groundbreaking UFO Video Just Released By Chilean Navy

An exceptional nine-minute Navy video of a UFO displaying highly unusual behavior, studied by Chilean authorities for the last two years, is now being released to the public. The CEFAA - the Chilean government agency which investigates UFOs, or UAP (unidentified aerial phenomena), has been in charge of the investigation. Located within the DGAC, the equivalent of our FAA but under the jurisdiction of the Chilean Air Force, CEFAA has committees of military experts, technicians and academics from many disciplines. None of them have been able to explain the strange flying object captured by two experienced Navy officers from a helicopter.

The Chilean government agency always makes its cases public when an investigation is complete, and acknowledges the existence of UAP when a case merits such a conclusion.

General Ricardo Bermúdez, Director of CEFAA during the investigation, told me that “We do not know what it was, but we do know what it was not.” And “what it is not” comprises a long list of conventional explanations. 



Witness spots UFO while waiting for rocket launch

The events occurred about 8:15 p.m. on January 19, 2017.
“My husband and I were in the viewing bleachers for the launch of the Atlas V rocket carrying a missile detecting satellite,” the witness stated. “We were in a launch delay. I was standing in the bleachers and others were sitting.”

The witness says she was staring at the sky as she had heard that UFOs sometimes frequent launches.

“I was looking towards the east and suddenly I saw an extremely bright, yellow/green light and it was wide, and it was close. It was horizontal to the ground and it streaked by us. I yelled, ‘Look’ and people in the stands caught a glimpse. It was so fast that many missed it, but some didn’t. The woman behind me who was sitting down and just caught a glimpse said it was a meteor. I said, no, there was something in it.”



CIA release report detailing UFO sightings in India

One report in particular which was curated on April 11, 1968, details UFO sightings on six separate incidents spanning from Ladakh (in India), Sikkim, Nepal and Bhutan from February to March of the same year.

The information report which describes “particulars of bright objects seen over south Ladakh, north east Nepal, north Sikkim and western Bhutan,” specifies the date, local time, area, direction of flight and particulars of the object.



Some scientific explanations for alien abduction that aren’t so out of this world

Belief in aliens has increased steadily since the birth of modern alien research in the 1940s and 1950s, following the news surrounding a classified US military project at Roswell Air Force Base, New Mexico. Surveys in Western cultures estimated belief in aliens to be as high as 50% in 2015. And despite the fact that it is considered rare, a significant number of people also believe they have experienced alien abduction.
…
Mixed evidence supports the theory that fantasy-prone people engage in elaborate imaginings and often confuse fantasy with reality. There are also other psychological explanations, such as dissociation – where an individual’s mental processes detach from each other and from reality, often in response to extreme or stressful life events. A tendency towards being fantasy-prone and dissociation has been linked in studies to childhood trauma and hypnotic suggestibility.

Psychologists argue that hypnosis encourages the creation and recall of detailed fantasies. For example, Betty and Barney Hill’s account was typical of reported alien encounters: medical examinations or procedures, communication with alien captors, a powerful, mystical feeling, tours of spaceships and journeys to other planets before being returned to the car. And it was under hypnosis that these “missing memories” were “recovered”.

It’s for these reasons that it’s believed alien abduction experiences may arise from a combination of personality characteristics and susceptibility to false memories.
…
None of this is to say that many people who believe they have experienced alien abduction are liars, merely that their accounts and experiences can be explained through recourse to theories with a scientific basis. There are many logical, plausible scientific explanations, none of which rely upon the existence of aliens. However, it should also be noted that not all reported alien abduction experiences can be easily explained by any of these scientific theories – and this throws up many more questions.



Flashes from an Unknown Source Far Beyond the Milky Way 

Perhaps the source "is a dwarf galaxy that contains a supermassive black hole, or is the nucleus of a disrupted galaxy or even just an isolated black hole,” Heino Falcke, a radio astronomer and astroparticle physicist at Radboud University Nijmegen in the Netherlands told the LA Times about mystery milliseconds-long flashes detected by researchers at Cornell University and a global team. “Maybe the persistent source is something completely different – for example, an exploding star ‘disguised’ to look like a black hole. And are these bursts made by the black hole itself, or by something else in orbit around it? After all, supermassive black holes are typically surrounded by dense star clusters."

Once thinking these bursts had emanated from within the Milky Way galaxy, or from cosmic neighbors, the astronomers now confirm that they are long-distance flashes from across the universe – more than 3 billion light-years away, according to a new report published Jan. 4 in the journal Nature.

“Because these flashes last only a millisecond, you can’t just go back and look at that patch of sky at a different time and catch that fast radio burst,” said Shami Chatterjee, an astronomer at Cornell University and leader of the Nature paper. “You have to be looking at that right millisecond to be able to catch a fast radio burst. These radio flashes must have enormous amounts of energy to be visible from over 3 billion light-years away.”

 Lettre ouverte à Monsieur Jean-Paul AGUTTES Responsable du GEIPAN
Objet: Déni d’évènements historiques liés au Phénomènes Aériens Non Identifiés

L’Académie d’Ufologie tient à renouveler l’affirmation de sa différence d’appréciation du phénomène ovni et à informer les citoyens et les ufologues de son désaccord total avec les propos tenus aux participants de la réunion publique d’Ovnis-Paris le 12 avril à La Défense…
…
Nous savons que le rôle du Geipan est de s’efforcer de banaliser les informations recueillies sur les PANs et de ne pas retenir l’hypothèse extraterrestre qui est pourtant la plus importante en ce qui concerne la survie de notre civilisation. Cette hypothèse a été retenue comme la plus probable par le rapport COMETA. Déjà en octobre 1952 le FBI écrivait que l’US Air-Force envisageait sérieusement cette hypothèse. Pourtant en 1948 elle avait été présentée par le personnel du projet SIGN au Général Vandenberg Chef d’État Major de l’US Air-Force, qui l’avait écartée comme étant inacceptable (ces informations sont basées sur des documents d’un de nos adhérents, reçus de l’administration américaine dans le cadre de le FOIPA). Le CNES-GEIPAN a adopté cette même attitude négationniste de déni de l’évidence et d’embargo sur la vérité concernant le phénomène ovni.



Interview du GEIPAN : "Le jour où l’on aura une preuve de l’hypothèse extraterrestre on sera ravi de l’annoncer"

Le 10 février 2016 Xavier PASSOT, responsable du CNES/GEIPAN (Centre National d’Etudes Spatiales/Groupe d’Etudes et d’Informations sur les Phénomènes Aérospatiaux Non Identifiés) était l’invité de l’Institut des Hautes Etudes de Défense Nationale (IHEDN AR 14 région lyonnaise). Sur la base de défense de Lyon, devant un parterre d’une centaine de personnalités militaires et civiles, ainsi que devant quelques ufologues invités, il donnait une conférence sur les phénomènes aérospatiaux non identifiés. Jean-Pierre TROADEC (Auditeur de l’IHEDN et chef d’escadron – RC – de la Gendarmerie nationale) était l’instigateur de cet évènement, au moment même où Xavier PASSOT quittait ses fonctions, passant le relais à Jean-Paul AGUTTES le nouveau responsable, actuel, du CNES/GEIPAN. L’occasion pour Xavier PASSOT de faire un bilan de sa direction du "département ovni du centre spatial".

Votre conviction en votre âme et conscience, sur les ovnis ?

Entre l'inconnu et l'hypothèse extraterrestre, on a deux étapes à franchir. Premièrement : est-ce-que cet inconnu représente de vrais objets matériels ? Pour l'instant, je n'en suis pas convaincu. La seconde étape, dans la mesure où on a affaire à des objets matériels, pose la question de leur origine ouvrant à une seconde série d'hypothèses. Aujourd'hui, ce que je peux juste constater, c'est qu'il y a des cas que je n'explique pas. Ça, on est d'accord là-dessus. Mais même s'ils sont nombreux, je ne peux pas certifier, prouver, qu'il s'agisse d'engins « tôles et boulons Â» derrière.



Les faits:
Le 23 novembre 2014, l'astronaute Samantha Cristoforetti de l’ESA, en communication avec le sol, était occupée à l'extérieur de la station spatiale. Soudain une lumière orangée a éclairé la surface de la station. De plus en plus intense, rougeoyante, la lumière attire naturellement l'attention de Samatha qui se retourne et aperçois avec surprise un objet orangé intense puissament lumineux. Elle ne peut retenir un cri de surprise.




Jaime Maussan: - Le 19 septembre 2006, la mission STS 115 de la navette ATLANTIS est incapable de revenir sur Terre. Elle doit attendre 24 heures à cause d’un objet qui interfère avec sa trajectoire. L’objet la suit depuis plusieurs heures. Aucune explication officielle n’a jamais été donnée par la NASA. Lorsque l'astronaute, Mary Anne Stefany Shyn-Piper, essaie d’expliquer ce qui s’est passé, elle s'effondre. Elle essaie de nouveau et s’évanouit encore une fois. Quelle histoire, n’est-ce pas !

A 11h45, le 9 septembre 2006, la navette ATLANTIS effectuant la mission STS-115 avait été lancée comme prévu depuis le complexe 30-9 situé au centre spatial Kennedy en Floride. Cependant, la NASA avait retardé le programme de retour d’un jour, à cause d'une rencontre avec un objet le 19 septembre. Un objet qui demeurait dans les hautes couches de l’atmosphère depuis 24 heures rendait impossible sa trajectoire de retour.
Bien que la NASA ait d’abord annoncé qu’il s’agissait de débris spatiaux, de glace ou même d’un sac, elle reconnut finalement ignorer la nature de l'objet. La NASA, employa les termes "d'objet étranger".


Qu'est ce que le SCEAU ?

Le SCEAU/Archives OVNI est une association sans but lucratif régie par la loi du 1er juillet 1901 dont les statuts sont parus au Journal Officiel du 23 mai 1990. Il a pour objet d'assurer la sauvegarde à long terme du patrimoine ufologique, à savoir tous livres, magazines, courriers, rapports d'enquête, études, coupures de presse et autres documents écrits, audiovisuels ou électroniques issus de la recherche sur les OVNI. Le SCEAU (acronyme de « Sauvegarde et Conservation des Etudes et Archives Ufologiques Â») est né du désolant constat que trop souvent, lorsqu'une personne qui a étudié cette question décède ou cesse de s'y intéresser, les documents parfois très intéressants qu'elle possédait sont dispersés, disparaissent ou sont parfois même détruits par ses ayants-droits. Lorsqu'un groupe ufologique est dissous, il en est parfois de même et les archives sont abandonnées ou dispersées. Pour exemples le cas du GNEOVNI dans le Nord au cours des années 90 dont les archives ont été détruites suite à la vente d'un immeuble et à l'incompréhension du nouveau propriétaire ; celles de la revue LDLN en partie perdues suite à un grave problème de conservation ou celles de la Commission d'Enquête Ouranos (fondée en 1951) et dont une grande partie des archives fut détruite ou dispersée en 1972. Ce ne sont là que quelques exemples qui sont malheureusement trop nombreux *.



Association Québécoise d’Ufologie

En fonction depuis 1998, l’association permet d’y accueillir des gens de tous les milieux qui s’intéressent à la question des objets volants non identifiés (OVNI). L’association qui ne prône aucune idéologie ou hypothèse quant à la réalité ou non de ce phénomène, propose à ses membres une tribune pour s’exprimer, débattre et échanger des hypothèses sur ce mystère dont l’origine remonte aux temps anciens. À travers certaines activités, les gens peuvent venir donner leur point de vue sans aucun souci de censure. Naturellement, l’AQU fait également de la recherche et tente d’éclaircir avec ses enquêteurs les différents cas d’observations que le public lui soumet. En gardant toujours une ouverture d’esprit mais une rigueur dans leurs actions, les enquêteurs tenteront de répondre honnêtement à ces nouveaux cas d’observations.



Le nombre d’observations d’OVNI explose dans le Massachusetts

NASA's Kepler Mission Announces Largest Collection of Planets Ever Discovered

NASA's Kepler mission has verified 1,284 new planets – the single largest finding of planets to date.
“This announcement more than doubles the number of confirmed planets from Kepler,” said Ellen Stofan, chief scientist at NASA Headquarters in Washington. “This gives us hope that somewhere out there, around a star much like ours, we can eventually discover another Earth.” 

Analysis was performed on the Kepler space telescope’s July 2015 planet candidate catalog, which identified 4,302 potential planets. For 1,284 of the candidates, the probability of being a planet is greater than 99 percent – the minimum required to earn the status of “planet.” An additional 1,327 candidates are more likely than not to be actual planets, but they do not meet the 99 percent threshold and will require additional study. The remaining 707 are more likely to be some other astrophysical phenomena. This analysis also validated 984 candidates previously verified by other techniques.

"Before the Kepler space telescope launched, we did not know whether exoplanets were rare or common in the galaxy. Thanks to Kepler and the research community, we now know there could be more planets than stars,” said Paul Hertz, Astrophysics Division director at NASA Headquarters. "This knowledge informs the future missions that are needed to take us ever-closer to finding out whether we are alone in the universe."



Alleged ET Related UFOs and ET Presence in the Peruvian Jungle

On Monday April 16 and 17, 2016, there were possible UFO landings and strange presences in the Amazon jungle of Perú. The events under investigation by Peruvian UFO researchers took place in “San Gabriel de Varadero” (about 1.5 – 3 hrs distant by boat from the city of Yurimaguas (using a canoe with propeller engines called “Peque Peque” because of the thup thup thup thup noise it makes) from the city of Yurimaguas in the Department of Loreto, Peru, in the Amazon Jungle. On Monday, April 16, 2016, between 8 and 9 PM (they go to bed early in the jungle), a woman called Agripina Guanze was sleeping with her sister and sons and was awakened by a strong sound like bird wing flapping and that of a kitchen blender then a strong light come into her bedroom as if a searchlight was pointing from the outside. She then saw 4 shining semi spherical objects flashing red and green lights like those of a traffic light and she allegedly felt that something was coming down. Apparently 2 of the objects landed in her garden about eight (8) meters from her house. They are described as about one meter (3.3 feet) in size. Frightened, she hid in her house, called the local authorities by phone and alerted the community awakening other members of the village. The alarmed villagers then communicated with a radio station.



Ohio UFO video: ‘Mind-blowing’ UFO flying over Ohio Air Force Base sparks awe

The 14-minute video of a UFO flying over the Wright-Patterson Air Force Base in Ohio is creating an internet buzz. The people who filmed the UFO video near the Ohio military base described the experience of witnessing the unidentified flying objects as utterly unbelievable.

As Fox News Science reports on May 29, the Ohio UFO video is just the latest report of unidentified flying objects near the Wright-Patterson Air Force Base. The base, which is located near Dayton, Ohio, was the home of Project Blue Book.



The long, strange history of John Podesta’s space alien obsession

So every time there's a news article about where Hillary Clinton adviser (and former Bill Clinton chief of staff) John Podesta talks about how President Hillary Clinton would release classified information about UFOs -- as he did again on Thursday -- I'm led to wonder. Is he just taking the joke too far? Has he committed so completely to the bit that now he just sort of answers the questions about space aliens without blinking? Or ... does he think that the government has information about visits from outer space that should be shared more widely?
…
Podesta started as deputy chief of staff for Clinton in 1997 and stayed with the president until the inauguration of George W. Bush. He himself was apparently somewhat obsessed with aliens. In 1998, The Post quoted Press Secretary Mike McCurry. "John can get totally maniacal and phobic on certain subjects," McCurry said. "He's been known to pick up the phone to call the Air Force and ask them what's going on in Area 51."



Distant Rocky World Could Be Friendly for Life

In good news for alien-seekers, scientists have come up with more evidence that a distant rocky world is likely habitable -- even given a range of atmospheric conditions.
Kepler-62f was announced in 2013 as the smallest "habitable zone" planet ever found at that time. It's just 40 percent larger than Earth and lives about 1,200 light-years away in the Lyra constellation. It was discovered by the Kepler space telescope, but not much is known yet about the shape of its orbit (this likely requires more telescope time to figure out).

The "habitable zone" is usually defined as the region nearby a star where liquid water was possible. But this depends on several factors, such as how much heat the star emits, the orbit of the planet and what the atmospheric composition of the planet's atmosphere is. Luckily for Kepler-62f, scientists found there are a range of scenarios where Kepler-62f stays habitable.

Un regard sociologique sur les manifestations OVNI

Depuis les années cinquante, la solidité du dossier ovni ne cesse de se confirmer. Les témoignages provenant de tous les continents, faits par des observateurs de toute nationalité, de tout niveau social, de toute culture, de toute croyance religieuse abondent. La nature transnationale et transculturelle des manifestations est indéniable. A l'instar de n'importe quel évènement, les manifestations ovnis sont donc perceptibles par tous et chacun peut un jour en devenir l'observateur.

Malgré l'immense diversité des témoins, les descriptions, les photos, les vidéos, les signatures radars ou sonars, sont semblables. Il y a donc une grande unicité des manifestations.
Cette succession d’observations surprenantes se poursuit depuis de nombreuses générations (1). Et les manifestations sont quelques fois observées par un nombre si considérable de témoins, qu'elles contraignent indirectement les médias, même les plus fermés, à présenter le dossier.

Depuis la seconde partie du XXème siècle, l’opinion publique, sur le sujet, est soumise régulièrement à de fortes secousses. Elle n’a pas cessé, malgré le silence des autorités et contre l’opinion des milieux scientifiques, de progresser vers une croyance en la réalité des ovnis(2). Dans le domaine politique, les gouvernements ont plus d’une fois vu s’imposer l’obligation de réagir face aux interrogations des médias. En France, les déclarations officielles ont invariablement consisté à calmer les esprits en réduisant l’importance du sujet et en affirmant le contrôle total de la situation par les autorités…



OVNIS : l’incroyable vérité

Les OVNIS existent ! Loin d’être une affabulation, cette affirmation résulte de décennies d’observations et d’investigations, au plus haut niveau de l’Etat, dans plusieurs pays. Pilotes, officiers, hauts responsables en témoignent. Gros plan sur une réalité qui bouscule nos schémas de pensée.

Belgique, novembre 1989. En fin d’après-midi, Heinrich Nicoll et Hubert Von Montigny aperçoivent un champ de lumière d’une grande intensité. Ils s’approchent… Au-dessus, plane un objet triangulaire, irradiant par moments d’un faisceau rouge. Délire d’étudiants ? Les deux hommes sont des policiers en patrouille. Hallucination ? Le même soir, 250 personnes rapportent aux autorités des observations identiques.

Pendant près de deux ans, ces apparitions se répètent. Des milliers de belges en sont témoins – parmi lesquels des ingénieurs, des militaires, des journalistes, des hauts fonctionnaires… Prenant l’affaire très au sérieux, l’Etat lance des investigations, mobilise des spécialistes. Peut-il s’agir d’un avion furtif ou d’un engin secret des USA ? Réponse négative du gouvernement américain – pourquoi aurait-il investi sans autorisation l’espace aérien belge, à la vue de tous ?

De cas en cas, les experts étudient, échafaudent des hypothèses, les testent… les invalident. Ce n’est pas un phénomène météorologique, affirment-ils, ni un hélicoptère, un appareil militaire, un ULM, un ballon ou quoi que ce soit de connu. « Parmi les 2000 cas rapportés, 650 ont fait l’objet de recherches, 500 restent inexpliqués », commente le Général Wilfried De Brouwer, alors Chef des opérations de l’Armée de l’air belge. Cet ancien pilote de chasse et cadre de l’OTAN est formel : il y a bien eu au-dessus de la Belgique une vague d’OVNIS – objets volants non identifiés.



Sociologie, récit et ovnis : rencontres d'un autre type

Après s'être intéressé aux stratégies discursives des astrologues, le sociologue Arnaud Esquerre poursuit son travail sur le langage en s'attaquant cette fois à la structure des récits de ceux qui disent avoir été témoins de phénomènes aériens non identifiés.



Le satellite Hitomi perdu dans l'espace à tout jamais ?

Depuis plus d'une semaine, les contrôleurs au sol de l'Agence spatiale japonaise (Jaxa) tentent sans succès de reprendre le contrôle du satellite Hitomi. Contrairement à ce qui a pu être envisagé un moment, l'appareil n'a pas été percuté par un débris spatial ni par des micrométéorites. Un ennui technique significatif est en réalité à l'origine de sa panne.

L’adage « pas de nouvelle, bonne nouvelle » ne s’applique pas au satellite Hitomi de l'Agence spatiale japonaise, la Jaxa. Son contact a été perdu le weekend dernier. L'appareil est en effet tombé subitement en panne pour une raison inconnue et les responsables de la mission ne sont pas parvenus à reprendre le contrôle du satellite.

Depuis la semaine dernière, la situation a très peu évolué. Cinq ou six débris spatiaux, et vraisemblablement beaucoup d’autres de plus petites tailles, évoluent toujours de concert avec le satellite. Ce dernier est toujours en rotation sur lui-même et émet de temps à autre quelques signaux d’une durée si courte qu’aucune information ne peut en être extraite.

Il y a toutefois une avancée dans l’enquête en cours pour comprendre les raisons de la perte de contrôle de Hitomi. En effet, l’organisme américain qui surveille les satellites et débris spatiaux a certifié aux Japonais que leur satellite n’avait pas été percuté par un débris ou un bolide avant l’apparition des éléments qui l'entourent. Il a daté à dimanche 27 mars, à 01 h 42 TU (à plus ou moins 11 minutes), l’apparition des débris autour du satellite.



Hillary Clinton ne divulguera rien de plus que les autres Présidents

Le discours d’Hillary Clinton est clair:
– si la Sécurité Intérieure ne l’autorise pas à divulguer elle ne le fera pas. Comme tous les dossiers ovnis (pas les confusions ni les inventions) relèvent de la sécurité nationale, elle annonce bien qu’elle ne fera rien de plus que les autres.
– elle « pense que les gens voient des choses, mais elle ne sait pas ce que c’est… Â» ; elle ne se souvient donc plus de l’initiative Rockefeller dans laquelle elle fût impliquée avec un rôle majeur.
A mon avis, elle a été « briefée Â» et elle ne s’impliquera pas dans une opération de type « divulgation Â» ou toute autre initiative qui pourrait contrarier « l’establishment Â» .

3 Février 1967 – Une journée chargée en observations d’ovnis

3 FEVRIER 1967   …………  LIMA PEROU
… Au bout d’un moment l’ovni a dépassé l’avion et s’est arrêté juste au dessus d’eux. A cet instant ils ont remarqué une oscillation à gauche  de 15° sur leur boussole radio, puis  une oscillation de 20° à droite  sans s’arrêter et toutes les lumières dans la cabine principale ont commencé à diminuer d’intensité.  Puis, tandis que  les lumières fluorescentes dans le cockpit s’éteignaient et toutes les réceptions radio s’interrompaient   il y eu  un peu de bruit statique.
3 Février  1967;  Piggott, ARKANSAS
De nombreux témoins ont vu manœuvrer des objets avec des dômes et des lumières qui clignotaient...
3 Février  1967;Lindsborg, KANSAS
19:40 CST (20:40 EST). Cinq personnes ont observé un disque ou une ellipse qui a d’abord volé comme un avion, mais s’est déplacé ensuite de manière   irrégulière et saccadée…
3 Février  1967; Hamilton, Ontario, CANADA
20:30  EST. Un homme a vu un objet dont il a estimé la taille à 30 pieds de diamètre et 15 pieds de large avec une rangée de lumières blanches et une lumière de couleur mandarine en dessous…



L’Éthique du contact

Nous remarquons d’abord que la compétition pour les ressources fait partie intégrante de la nature. Nous voyons ensuite que l’intervention d’un groupe ethnique chez un autre s’appuie toujours sur l’intérêt de ce premier au détriment du second, lequel subit un impact destructif sur sa culture et sur la liberté de son peuple. Finalement, nous voyons que le fort domine toujours le faible, quand il le peut.

Bien qu’il soit concevable que ces races d’extraterrestres nous visitant soient une exception à la règle, il faudrait qu’elles prouvent sans l’ombre d’un doute que c’est bien le cas en respectant l’humanité dans son droit intrinsèque d’évaluer toute proposition de visite. Cela ne s’est  certainement pas encore produit. La réalité est tout autre.

Notre expérience de contact, jusqu’à maintenant, nous force à constater qu’à titre de peuple indigène de ce monde, nous avons vu notre autorité déniée et nos droits de propriété bafoués. Les « visiteurs » ont suivi leur propre ordre du jour, sans se préoccuper d’obtenir l’approbation de la race humaine ni attendre une participation de celle-ci basée sur une information juste et pertinente.



Looking for answers on UFOs, aliens

About 41 years ago, a man said he was abducted by a UFO while returning home from work in Arizona.  His name is Travis Walton, and he reappeared five days after his alleged abduction on November 5, 1975.

He's just one of the people featured in the upcoming photo book, "Phenomena," which is an investigative look into American beliefs about UFOs and aliens. The book is a project by Danish photographers Peter Helles Eriksen, Sara Galbiatiand Tobias Selnaes Markussen.

"We just had a mutual interest in it," Galbiati said. "Not as us being believers and talking about how we believe in UFOs, but more in that we thought that it was interesting that there was this group of people that believes so much in this that they see the world completely different than the majority."

Two Curious but Newsworthy Events in Peru

“Yesterday I had an interview with CNN about a theme that would seem exotic; that would seem to be part of science fiction but it is not. (It was) about the extraterrestrials.” (Alejandro Toledo, former President of Peru).

Thus, former Peruvian President Alejandro Toledo recently mentioned the extraterrestrial issue  in a serious – not in a tongue and cheek – manner. After these words were pronounced, there was a brief silence in the room. It all took place at Hotel Estelar (Stellar Hotel!) in the district of Miraflores, in Lima, Perú on Tuesday March 22nd 2016.
…
Interestingly (and this is also newsworthy),  a few days later, on the late evening of March 28, unknown objects were seen over a low income district in northern part of Lima called “Carabayllo” and they were cell-phone filmed and witnessed by a number of people. Are they man-made, natural or truly anomalous objects? This has to be found. There also were circling search lights on the sky in one of the videos but with blue orbs in the background. Was all of it concocted or perhaps someone pointed the search lights at the blue orbs to get a response?

Hawking: We Probably Won't Find Aliens Soon

Hawking said it’s not likely that scientists will find intelligent alien life in the next 20 years. “The probability is low, probably,” he said. But the cosmologist did mention one caveat.

13 Ways to Hunt Intelligent Aliens
“The discoveries of the Kepler mission suggest that there are billions of habitable planets in our galaxy alone,” Hawking said. “There are at least a hundred billion galaxies in the visible universe, so it seems likely that there are others out there.”

Hawking has famously predicted that intelligent aliens might threaten humankind. Indeed, when asked yesterday about what Earthlings should do if we come across intelligent alien life, he said, “We should hope that they don’t find us.”



Is Religion From Outer Space?

In the sixteenth century, the good-looking Italian cosmologist Giordano Bruno published his opinion that the universe consisted of infinite solar systems with infinite habitable planets housing an infinite array of beings.

To Bruno’s mind, as a devout Christian, an infinite God could conjure these things in a day and a half of creative labor and thereafter manage the menagerie for His entire life.

But the notion of extra-earth beings did not align perfectly with the reigning Christian orthodoxy of sixteenth-century Europe, and so handsome Giordano Bruno and his handsomely bound books were burned to cinders.



Thomas E. Reed – Family Abduction
Date of Event / Case File: 01/01/1965

The historic UFO case of the Reed Family, was assigned a Valleeclassification of “CE4” (close encounter of the 4th kind), with a case category of 3 (physical evidence). The case has many layers and is deeply entwined and remains one of a few CE4 cases to be mentioned within the walls of the United Nations.

The evidence in this case would include a significant amount of radiation, and strong magnetic fields, and is one of a few to have been collected and documented by those in law enforcement. It includes a history of testimony gleaned from conscious recollections, an abundance of documentation, administrative testing, and official reports, followed by dark consequences. The history involves Marian Burrows, grandmother, Nancy Reed, mother, and the two brothers, Thom and Matthew.

In the quaint town of Sheffield, Massachusetts, in the 1960’s, Thomas, age 6, and his younger brother Matthew, experienced life altering events. Due to their vulnerable age, these encounters had an enormous impact on them, crushing their belief system, and denying the two boys of their reality, normalcy, and spirit.



Humans have pondered aliens since medieval times

Scientific inquiry into the existence of extraterrestrial intelligence still often begins by pondering Fermi’s paradox: The universe is vast and old, so advanced civilizations should have matured enough by now to send emissaries to Earth. Yet none have. Fermi suspected that it wasn’t feasible or that aliens didn’t think visiting Earth was worth the trouble. Others concluded that they simply don’t exist. Recent investigations indicate that harsh environments may snuff out nascent life long before it evolves the intelligence necessary for sending messages or traveling through space.

In any event, Fermi’s question did not launch humankind’s concern with visitors from other planets. Imagining other worlds, and the possibility of intelligent life-forms inhabiting them, did not originate with modern science or in speculative fiction. In the ancient world, philosophers argued about the possibility of multiple universes; in the Middle Ages the question of the “plurality of worlds” and possible inhabitants occupied the deepest of thinkers, spawning intricate and controversial philosophical, theological and astronomical debate. Far from being a merely modern preoccupation, life beyond Earth has long been a burning issue animating the human race’s desire to understand itself, and its place in the cosmos.

Vie extraterrestre : à deux doigts de la réponse

C'est ce qu'a voulu démontrer Robert Lamontagne, astrophysicien à l'Université de Montréal et directeur du télescope de l'observatoire du Mont-Mégantic, dans une captivante conférence qui a eu lieu la semaine dernière au Café Clovis du Cégep de Drummondville.
…
«Plus nos technologies progressent, plus nous trouvons des exoplanètes dont la masse se rapproche de celle de la terre et plus elles sont à une distance semblable à celle qui sépare notre terre du soleil. Trop près c'est trop chaud, trop loin c'est trop froid pour que naisse la vie», a expliqué l'astrophysicien.
…
Robert Lamontagne, qui est également membre de l'iREx (Institut de recherche sur les exoplanètes), se dit confiant que les instruments à venir permettront de faire un bond de géant au début des années 2020. Il a parlé de TESS (Transiting Exoplanet Survey Satellite), de la NASA, qui verra le jour vers 2018 avec la mission de balayer le ciel afin de trouver spécifiquement des exoplanètes. Il y a également le JWST (James Webb Space Telescope) qui sera aussi en fonction en octobre 2018, qui sera 10 fois plus puissant que Hubble. Et surtout, il y a le TMT (Trente Mètres Téléscope), un observatoire astronomique terrestre capable d'observer depuis le proche ultraviolet jusqu'à l'infrarouge moyen (500 fois plus puissant que le Mont-Mégantic), et le EELT (European Extremely Large Telescope) avec son miroir primaire d'un diamètre de 39 mètres, qui doit entrer en service en 2024.



Interview du spationaute Jean-François Clervoy sur les ovnis et l'espace

En dehors de sa prestigieuse carrière de spationaute, Jean-François Clervoy manifeste une vive curiosité pour les phénomènes qui restent encore inexpliqués par la science. Notons qu’il fait partie du comité de soutien de l’Institut de recherche sur les expériences extraordinaires (INREES) dont l’objectif est de sensibiliser les professionnels de la santé et le grand public aux expériences extraordinaires qu’un certain nombre de personnes disent avoir vécues (Expérience de mort imminente, observations d’ovnis, enlèvements par des ovnis, contact avec les défunts, etc.).

En ce qui concerne le phénomène ovni, il participe aux travaux de la commission Sigma devenue plus tard Sigma2 placée sous la direction du très dynamique Luc Dini (Diplômé de l’École Nationale Supérieure d’Ingénieurs de Constructions Aéronautiques, de l’École Nationale Supérieure des Ingénieurs des études et techniques d’armement, "Directeur Business Development Missile Defense" chez Thales Air Systems, auditeur à l’IHEDN) qui se révèle être un animateur particulièrement actif dont l’ambition avouée est de faire avancer le dossier ovni. Selon Clervoy, Luc Dini n’est pas hostile à l’idée de communiquer au public les résultats des travaux de la Commission. 



Préparation des ufologues à la Divulgation

Comme la divulgation se rapproche, voici ce à quoi vous pouvez vous attendre :
1) Des canulars
Il y a une composante de tricherie dans l’ADN humain. Nous aimons faire des canulars, des bons coups, des farces. C’est ce que nous faisons. Les canulars OVNI/ ET vont augmenter, peut-être même de façon spectaculaire…

2) Des prédictions
Les gens vont s’exciter et les prédictions vont suivre. Ceci est également la nature humaine et c’est compréhensible…

3) De faux témoins
La divulgation sera le plus grand spectacle sur Terre. Beaucoup de gens voudront être sur la scène, qu’ils aient ou non un lien avec la question elle-même.

4) De vrais témoins
Comme la divulgation approche beaucoup de témoins légitime, comme les militaires, les agents de renseignement, les témoins politiques pourront sentir qu’ils peuvent enfin aller de l’avant. De toute évidence, l’évaluation de ce processus sera rendu compliquée par les faux témoignages. Tout ce qui peut être demandé est que le public et les médias fassent de leur mieux pour appliquer la raison et le bon sens.

5) Des récits élaborés
Ce sont essentiellement des canulars d’un niveau très avancé. Il vous sera présenté de longues histoires d’une grande complexité. Elles seront très divertissantes mais elles seront complètement fausses.

6) Une opposition
La divulgation sera l’événement le plus profond de l’histoire humaine. Nombreux sont ceux qui estiment qu’il n’en est pas encore temps… Nous devrions attendre que nous soyons plus avancés technologiquement ou spirituellement… Nous devrions laisser le gouvernement décider. Etc… Une partie de cette opposition consistera en des réflexions légitimes de préoccupation et une autre partie sera de la propagande.

7) De la désinformation
C’est la tâche qui sera la plus difficile à affronter pour le public et les médias...



Les intelligences “extraterrestres” et nous

Depuis des décennies et probablement depuis toujours, des intelligences extérieures semblent se manifester par les manœuvres de certains ovnis (Objets Volants Non Identifiés) ainsi qu'à l'occasion de rencontres rapprochées. Après quoi courent-elles ? Que projettent-elles ? Sommes-nous capables de les comprendre ? Et l’une des interrogations parmi les plus importantes : leurs comportements, leur conduite de nos relations s'appuient-ils sur une morale, ou bien, sur une compréhension du sens de notre existence ? Nos visiteurs possèdent-ils une connaissance ou une vision plus profonde pour ce qui concerne le sens et le destin de la Vie en général et de la nôtre en particulier ? Sur quoi notre monde pourrait-il s'appuyer pour comprendre le point de vue de nos visiteurs ? Sur quoi pourra-t-il s'appuyer pour garantir des relations harmonieuses avec eux ?



Les astronautes d'Apollo 10 ont entendu une musique étrange derrière la lune

La Nasa a rendu public l'enregistrement d'"une musique bizarre" entendue par l'équipage d'Apollo 10 en mai 1969 lors de leur survol de la face cachée de la Lune sans aucun contact radio avec la Terre.
…
Le cas de ces sifflements a été présenté dimanche soir sur la chaîne câblée Discovery dans le cadre de sa série intitulée "Les dossiers inexpliqués de la Nasa".
…
"Vous entendez ça? ce sifflement...", dit Eugen Cernan sur l'enregistrement. "C'est vraiment une musique bizarre", poursuit-il alors que leur vaisseau survole la face cachée de la Lune à 1.500 mètres d'altitude, coupé de tout contact radio avec la Terre.

Les trois astronautes ont jugé le phénomène tellement étrange qu'ils ont débattu du fait de savoir s'ils devaient ou pas le signaler au centre de contrôle à leur supérieurs, de crainte de ne pas être pris au sérieux et de compromettre leurs chances d'effectuer de futurs vols, selon l'émission de Discovery.



« Que veut l’Intervention ici sur Terre ? Â»

L’Intervention cherche à contrôler ce monde et les peuples de ce monde. Elle ne fait pas seulement cela pour atteindre ses propres objectifs de richesse et d’acquisition de ressources, mais pour servir de plus grandes puissances qui utiliseront secrètement l’Intervention pour prendre le contrôle du monde. Ces grandes puissances n’oseraient pas entrer dans le monde comme le fait maintenant l’Intervention, mais ils utiliseront ces forces moins scrupuleuses pour atteindre leurs propres buts d’influence et d’acquisition.

L’Intervention veut une humanité docile. Elle ne veut pas une humanité rebelle, car elle ne pourrait pas gérer cela. L’Intervention veut que l’humanité travaille en étant consentante – en croyant à ses buts, principes et promesses. Ceux-ci, bien sûr sont faux et trompeurs, et ça serait la plus grave des erreurs si l’humanité suivait ces mandats.

Donc, comprenez que vous avez maintenant la concurrence venue de l’univers – concurrence pour la valeur et les ressources de ce monde, pour sa position stratégique et pour les choses cachées ici sans que les humains en aient conscience, et qui sont d’une immense valeur à ces races de l’univers qui en ont conscience…

My time as a UFO investigator

Nick Pope investigated UFOs for a now-defunct British Ministry of Defence division. He argues it’s time for the programme to re-launch – for reasons that have nothing to do with small green men.
I worked for the MOD for 21 years. From 1991 to 1994, I was posted to a division where my duties included undertaking these investigations. It was a fascinating job, to say the least.

A UFO, it’s worth remembering, refers to any unidentified flying object – not necessarily an extraterrestrial one. While the MOD investigations were aimed at determining whether there was evidence of any threat, we were thinking more about Russians than Martians. The theory was that some sightings might involve Soviet spy planes or bombers probing our air defences to try to evaluate the effectiveness of our radar systems, aircraft and pilots. The British government’s position was virtually identical to that of the US, where UFO sightings had been investigated by the United States Air Force (USAF) since 1947, in what later became known as Project Blue Book.
…
There is huge public interest in this. When the UK got its Freedom of Information Act, the MOD received more requests about UFOs than any other subject. Prompted by this interest, an ongoing project to declassify the MOD’s UFO files has resulted in the release of nearly 60,000 pages of documentation, including sighting reports from the public and formerly-classified MOD papers. Each time a batch of UFO files is released, it makes headline news around the world. The final batch of files will be made public this year.



Aaron Rodgers: NFL star speaks about his wild close encounter with UFO

"It was a large orange, left-to-right-moving object. Because of the overcast nature of the night and the snow, you couldn't make out, it was behind the clouds we were seeing, but it was definitively large in the night sky, moving from left to right," Rodgers continued. "Again, it was like 12:30 at night here. It was me, Steve, and his brother that saw it."

"And it goes out of sight and we look at each other and go, 'What in the f--- was that?'" Rodgers recalled. "You could hear it moving. When it had been out of sight for like 30 seconds -- and when I say 30 seconds, it felt like five minutes -- at the time, we were kind of in shock."

Aaron Rodger’s close encounter with the UFO took place in 2005, and since then, he has learned quite a bit about those unusual sightings:
"Now, if you know anything about UFO sightings or you've done research, you know that a lot of times two things are connected to UFO sightings," Rodgers added to his UFO story. "One, is the presence of fighter jets. And two, there's a lot of sightings around nuclear power plants. So to tie it all together, the alarm we heard was from 30 miles out was a nuclear power plant that had an alarm that went off."



Mars named MUFON Marketing Director

…A former journalist and SIU grad, he headed several of his own business ventures before recently accepting his current job.
Q: So do you think your last name had any sway in getting the job?
A: "When I talked to the (director) initially, I said you're going to get an email and my last name is Mars. I said, 'I'm serious. That's my last name. And it's just a coincidence.'"
…
Q: What's John Mars' mission?
A: "There's just a lot of educating the public. I want to get the military involved more. And first responders. We need to take the drama out of aliens and invasions and the way I look at it objectively: There is other life out there. And let's see what's out there. Let's do the research."



Unexplained Formation of Objects on NASA Photograph from Space Shuttle STS-100

In March of 2016, a “viral” story resurfaced about a UFO in a NASA photograph, that was mysteriously ‘deleted’ from NASA’s website.  After investigation, the original link that showed the photograph in question was broken, it is likely due to the fact that the database simply was moved. The new source, once located, verifies the photograph is still available for download.  So, the story about it being “deleted” is largely untrue.

However, what IS true, is the fact that the photograph does show an unidentified “formation” of UFOs, whatever they may be. This page was created to help make sense of a largely incorrect story being circulated.

What are we looking at?
The photograph in question, which is verified as a genuine NASA photograph, has an unexplained formation of UFOs in the frame…



What's up in space

SLIGHT CHANCE OF METEORS: A new meteor shower could appear this week. According to theoretical modeling by Mikhail Maslov, Earth will pass through a sparse cloud of meteoroids from Comet 252P/LINEAR on March 28-30. The encounter could cause a minor shower of slow meteors emerging from a radiant near the star μ Leporis, south of the celestial equator. Little is known about meteors from 252P/LINEAR, so estimates of the meteor rate are very uncertain. Maslov's models suggest no more than 5 to 10 per hour.

SOLAR CYCLE CRASHING: Anyone wondering why the sun has been so quiet lately? The reason is shown in the graph below. The 11-year sunspot cycle is crashing.

For the past two years, the sunspot number has been dropping as the sun transitions from Solar Max to Solar Min. Fewer sunspots means there are fewer solar flares and coronal mass ejections (CMEs). As the explosions subside, we deem the sun "quiet."



High Altitutde Craft With Thrusters Transits The Moon

Many followers asked me to redo this clip so here it is. Shot well over a year ago, this clip shows a very high altitude craft with three rocket-like thrusters. The footage was shot in the daytime using an 8" telescope through a city light filter. This is why the footage looks to have been shot at night.


          Hubblecast 99: Hubble’s biggest discoveries — part 2        
To many, Hubble is best known for its stunning images of celestial objects, but among astronomers it is admired for the valuable data it delivers. Hubble has helped revolutionise astronomy, including shedding light on dark matter and dark energy, lifting the veil on black holes, and peering into the dusty regions around stars to image exoplanets. This new Hubblecast is the second part of an exploration of some of Hubble’s most important discoveries throughout its history.
          Hubblecast 97: Hubble, exoplanets and the hunt for life        
Since astronomers discovered that the stars in the sky are other suns, humanity has wondered if they are also orbited by planets and if those planets host alien life. Since the discovery of the first exoplanet only 25 years ago Hubble is among the many instruments trying to answer these questions. This new Hubblecast tells the story of what we know so far and what we can hope for in the future.
          Zeppelins: A Stairway to the Heavens?        
Before the space age, there was the airship age. Dirigibles were so popular in the early 20th century that a mooring for airships was fitted to the top of the Empire State Building upon its completion in 1931!

But, the mooring was only used once, and only for a couple minutes. It turns out that docking a giant blimp to a building over 1,000 feet tall is nearly impossible; the winds at that height are too strong. Soon after that first brief docking attempt, a Goodyear blimp also tried and failed to dock at the Empire State Building mooring. Its crew did manage to lower a stack of the evening newspapers down a 100 foot long line to the building roof, though! It seems the Empire State Building's airship docking port wasn't considered practical even when it was built. Its construction and attempts to use it were pretty much just a publicity stunt.

The failed attempt to turn the Empire State Building into a dirigible port foreshadowed the end of the airship era. The 1930s saw a rise in airship accidents (e.g., the Hindenburg disaster). Soon, airplanes overtook airships as much faster, more reliable, and safer. Since the 1930s, there's been very little need for airships as a means to transport people or objects. The few airships left in operation now satisfy a small niche market: they're an efficient way to float in place or cruise very, very slowly through the sky... and that's about all.

The evening I started writing this post on airships I found out that one of the U.S.'s few (maybe only?) private dirigible operators, Mountain View based Airship Ventures, is likely closing. CEO Brian Hall cited the tenfold increase in helium prices since the company's founding in 2007 as one of the challenges the company faced.

I think airships are so neat; I'm sad to see Airship Ventures struggle to make it, much in the same way that commercial passenger space travel struggles to become a viable industry. And speaking of space travel... did you know that airships are actually useful tools for space exploration?

An airship is the perfect vehicle to test a starshade. What's a starshade? It's a large disk that blocks the light from a distant star, allowing for observation of that star's exoplanets. Folks have contemplated launching a starshade to sit 80,000 miles in front of the James Webb space telescope, which will hopefully launch in 2018. An airship-mounted starshade could be tested before 2018. According to a Wired article from this past February, Airship Ventures' Eureka was going to fly a starshade in Spring 2013, to block star light for Earth-based exoplanet observations. With Airship Ventures closing, I guess that won't happen now. :-(

The Airship Eureka.

Even if the Airship Eureka doesn't fly again, it will have done its part to contribute to space exploration: it has hunted for meteorites! In April of this year, a minivan-sized meteorite exploded over northern California. Researchers were especially eager to collect fragments of the meteorite, since the asteroid it came from was of a relatively rare variety, the carbonaceous chrondite. This type of rock is full of the organic molecules that serve as the building blocks for life on Earth (and elsewhere?).

NASA and SETI paid to take Eureka out on a five-hour mission to search for bits of the exploded rock. The airship cruised slowly over the Sierra Nevada foothills, and the scientists on board looked for little impact craters, finding a dozen possible sites.

Circling back to CEO's explanation for why Airship Ventures is going out of business: helium prices have increased tenfold in the past five years. Why is helium getting so expensive? It's a fascinating question, actually. I'll talk about it in my next post.

La relación sísmica y el “cluster” Elenin

1 de Julio de 2011

Ya no podemos hablar de casualidades, y no podemos porque no hay tales. Tras el análisis realizado por Mensur Omerbashich, en el que se relacionaban las posiciones del “cluster” con la actividad sísmica la cuestión quedó pendiente de un nuevo análisis prometido en Elenin parte IV: ¿Sistema Solar, Perturbación de Oort, alteraciones geomagnéticas y TGTRPT?.

Ciertamente, tras el escenario de eventos recientes, tendremos que analizar de nuevo las órbitas y consideraciones relativas a posiciones del cometa “cluster” en las últimas semanas, algo que tendremos preparado en breve con los nuevos datos, tras verificar de nuevo toda la batería de imágenes disponibles sobre el evento y las hojas de trabajo que ya realizamos durante los meses de abril y mayo.

Elenin. Tercer análisis. Visualizando el cluster. ¿Perturbación de Sagitario?, Últimos datos sobre Elenin: Análisis de estructuras y fotos del cluster. Análisis detallado del Cometa Elenin. ¿Es la artificialidad del objeto la que hace imprevisible su órbita?

Pero está claro que existe una clara danza de los objetos que provienen de Oort La perturbación de Oort al descubierto: NEA Los objetos de Oort y su danza. Y esta perturbación se remonta a todo lo ya analizado y publicado en nuestro libro Publicación del e-book: Misterios de la Astrofísica: La perturbación de Sagitario. G 1.9+0.3. La falsa Supernova y la búsqueda de Nibiru.

En esta ocasión, veamos un experto independiente analizando algunas de las las posiciones y previsiones ya descritas por Mensur Omerbashich.

No creemos en las casualidades, aunque les dejamos que saquen sus propias conclusiones al respecto. Muy pronto, tendremos nuevos datos.

Advierten que aumenta día a día la chance
de que un asteroide choque con la Tierra

1 de Agosto de 2011

Un estudio del instituto alemán Max Planck de Astronomía señala que la probabilidad de que ocurra un evento catastrófico como el que se cree que exterminó a los dinosaurios aumentó constantemente desde hace 250 millones de años.

¿Será la Tierra embestida por un enorme asteroide como el se cree exterminó a los dinosaurios? Eso no se puede afirmar, pero científicos del El instituto alemán Max Planck de Astronomía (MPIA) sí establecieron que al menos las probabilidades de que eso ocurra aumentan día a día.


Un nuevo estudio de estos profesionales publicado en las Notas Mensuales de la Royal Astronomical Society, encontró patrones periódicos relacionados con la probabilidad de impactos de asteroides con la Tierra, que determinan que dicha chance ha aumentado de manera constante desde hace 250 millones de años hasta la actualidad.


La investigación se realizó a través de una teoría conocida como la "estadística bayesiana" (por el Teorema de Bayes), con la que el investigador del MPIA, Coryn Bailer-Jones, halló patrones de probabilidad en relación a este fenómeno.


Indicaron que el mecanismo propuesto para explicar estas variaciones es el movimiento periódico del sistema solar con respecto al plano principal de la galaxia. Según Bailer-Jones, este movimiento natural de la Vía Láctea influye en la presión gravitatoria de las estrellas remolcadoras de objetos de la nube de Oort, un depósito gigante de cometas a casi un año luz de distancia desde el Sol.


Estos cometas “tienen por costumbre salir de la 'nube', para iniciar un viaje al interior del sistema solar, por lo que son potenciales colisionadores de la Tierra”, explicó el astrónomo. Según el experto, los grandes impactos de cometas o asteroides con el planeta se han relacionado a lo largo de su historia con periodos de destrucción.


Además, señaló que a uno de estos impactos de asteroides se lo relaciona con la extinción de los dinosaurios hace 65 millones de años, y que habría ocasionado alrededor de 200 cráteres, algunos de ellos con cientos de kilómetros de diámetro.


Según el estudio, este hallazgo puede ser "de gran ayuda" que los científicos puedan calcular y advertir en qué períodos el planeta se encuentre más vulnerable a este tipo de impactos cósmicos.
