SETI Institute

Today I would like to share with you an idea for the International Women's day on March 8 2013.  If you work in an institution, university, or non-profit related to science, have you taken note of the number of women around you? In astronomy and planetary science, it is not too bad even if it is not perfect, but some "hard" science groups, like physics or computer science, clearly have a low proportion of women in their ranks. I will not elaborate on the reasons for such lack of representation; instead, I propose to focus on the bright side. Yes, there... read more ❯

"Mountain View, we have a problem..." NASA Kepler Manager at NASA Ames, Mountain View announced today that they interrupted the science operation of the spacecraft, due an issue with one of the reaction wheels.  Kepler is equipped with four reaction wheels which are used to accurately point the telescope. One failed in July 2012 and today the team announced that they detected issues with a second one. Kepler needs three reaction wheels to be used properly, if this one fails the mission is most likely over. That's not good news. The team detected an increase of friction on reaction wheel #4 on January... read more ❯

Tomorrow is the first day of the AGU Fall Meeting, in San Francisco, CA. I love this conference, not only because it is 30 min door-to-door from my house, but also because it is BIG... Last year there were ~27,000 registered geoscientists, and there is no reason there should be less of them this year. With more than 29 parallel sessions in diverse  topics such as Atmospheric Sciences, Hydrology, Natural Hazards, Biosphere, Volcanology, Cryosphere, Education and of course Planetary Sciences, plus several social events, and press conferences, it will be a feast for scientists, science reporters and the public. Several press conferences and... read more ❯

The Gemini Planet Imager team is joining the Cosmic Diary Network. GPI is the next generation adaptive optics instrument being built for the Gemini South Telescope. The goal is to image extrasolar planets orbiting nearby stars. The GPI team will use this blog to show the progress on the development of this instrument and discuss the science results which will be obtained in 2013. WHO: GPI is being built by a consortium of U.S. and Canadian institutions, funded by the Gemini Observatory, which is an international partnership comprising the U.S.A., U.K., Canada, Australia, Argentina, Brazil & Chile. WHEN: After more than 5 years of development (preliminary design review... read more ❯

Today I am feeling inspired and motivated. It could easily have not been the case since the day started with a massive crash of my email inbox, a difficult review of a recently submitted paper, and some issues with my simulation that I am planning to present at the ACM conference next week – not to mention a lack of sleep. Still, all of this became irrelevant when I watched NASA’s new promotional video attached below. Sometimes it is good to be reminded how lucky we are to be part of this adventure. Never in the history of mankind have we had access to... read more ❯

An update about the Sutter's Mill Meteorite that I mentioned yesterday. A few hours ago, I saw the pieces that Peter Jenniskens brought at the SETI Institute. I am not a meteorite expert but they indeed look like a carbonaceous chondrite meteorite. The fragments are black, with tiny white flecks scattered through the interior. On the surface, one can see black coating due to the heating during the passage through the Earth atmosphere. While watching them, I had this unreal... read more ❯

Join us on Wednesday, February 29, 2012 - 7:00pm at the Colloquium room of the SETI Institute to hear a talk by Andrew Nelson, Chief Operating Officer of XCOR. Title: The Trillion Dollar Space Enterprise --> Or How The Lynx Suborbital Vehicle Will Change The World by Andrew Nelson, Chief Operating Officer of XCOR Abstract: Fully resuable spacecraft are the critical enabler for regular, low cost and safe access to space, and such access will enable space utilization in ways we've only dreamed about in the past. Much as the early ARPANET laid the foundation... read more ❯

Kepler-16 is another great discovery coming from the Kepler telescope, the 10th NASA Discovery mission which is devoted to finding Earth-size exoplanets by monitoring variations of brightness due to transit. Today the Kepler team found a circumbinary exoplanet, an exoplanet orbiting a binary star system. Did they find Tatooine? In the large 105 deg2 field of view of the Kepler spacecraft, ~156,000 stars are being almost continuously observed by the 0.95m telescope. In 2010, the star number KIC... read more ❯

Last Tuesday July 19 at 3:25am PDT, several SETI REU students and colleagues from SETI institute and Observatoire de Paris were on the road. They were looking at the sky with  tiny telescopes and surrounding by complex instruments somewhere in the middle the Californian countryside to witness and record a rare event: the occultation of a bright 7-mag star by the double asteroid (90) Antiope. (90) Antiope is clearly a remarkable and unique binary asteroid. It is made of 2 large (~86 km) ellipsoidal components orbiting around their center of mass in 16.5 hours, describing a circular orbit with a... read more ❯

My previous post on the hibernation of the Allen Array Telescope got a lot of attention and I have been contacted by various people to discuss its impact on the institute and on my research. First of all, I should remind my readers that the SETI Institute is a research institution composed of three departments: - The Center for education and public outreach which manages the E/PO of various NASA projects such as Kepler and SOFIA and also our Research Experience for Undergraduates program. - The Carl Sagan Center for the Study of Life in the Universe composed of ~60 scientists who... read more ❯
