Astronomy: April 2013 Archives

Keith's note: When he was asked by Lamar Smith at House Science Committee hearing on NASA's FY 2014 budget why two James Webb Space Telescope instruments were late, Charlie Bolden then tried to push that off as bad news reports. Bolden went on to say that he has been adamant that he takes full responsibility for the progress of Webb. Smith then read from the recent GAO report "NASA: Assessments of Selected Large-Scale Projects" citing this passage:

"... In addition, only two instruments have been delivered for integration with ISIM and the other two instruments will be delivered at least 11 months late."

When Smith asked Bolden again about the two late Webb instrments, Bolden's reponse was: "That's news to me"

Kepler-62 Has Two Water Worlds Circling in its Habitable Zone

"In our solar system, only one planet is blessed with an ocean: Earth. Our home world is a rare, blue jewel compared to the deserts of Mercury, Venus and Mars. But what if our Sun had not one but two habitable ocean worlds? Astronomers have found such a planetary system orbiting the star Kepler-62."

New Earth-like Planets Found, CIW

"Theoretical modeling of the super-Earth planets, Kepler-62e and Kepler-62f, suggests that both could be solid, either rocky--or rocky with frozen water."

NASA's Kepler Discovers Smallest 'Habitable Zone' Planets to Date, NASA

"The Kepler-62 system has five planets; 62b, 62c, 62d, 62e and 62f. The Kepler-69 system has two planets; 69b and 69c. Kepler-62e, 62f and 69c are the super-Earth-size planets."

2013 STScI Spring Symposium and Habitable Worlds across Time and Space Cancelled, Space Telescope Science Institute

"We regret to announce that the 2013 STScI Spring Symposium, Habitable Worlds across Time and Space, has been cancelled. Space Telescope Science Institute operates as a NASA contractor. Our contractual obligations include support of workshops and seminars. In response to fiscal impacts resulting from the United States Government sequestration, NASA has temporarily suspended the contract authority and all funding that enables us to host conferences and seminars."

NASA Hosts Media Briefing to Discuss Kepler Planetary Discovery

"NASA will host a news briefing at 2 p.m. EDT, Thursday, April 18, to announce new discoveries from the agency's Kepler mission. The briefing will be held in the Syvertson Auditorium, Building N-201, at NASA's Ames Research Center in Moffett Field, Calif., and be broadcast live on NASA Television and on the agency's website."

Keith's note: Not that this has any indiciation of what will be announced but Lisa Kaltenegger's Kepler-related publications all focus on small, habitable extrasolar planets and moons. (search). Thomas Barclay's papers also focus on Kepler and extrasolar planets. (search). These papers (by other authors) "The detectability of habitable exomoons with Kepler" and "Where to Find Habitable "Earths" in Circumbinary Systems" were submitted to astro-ph last week.

AMS-02: Shining light on elusive dark matter, ESA

"The findings hint at a new phenomenon but it is unknown whether the positron ratio comes from dark energy particles colliding with each other or from pulsating stars in our galaxy that produce antimatter."

First Result from the Alpha Magnetic Spectrometer on the International Space Station: Precision Measurement of the Positron Fraction in Primary Cosmic Rays of 0.5-350 GeV, Physical Review Letters

"These observations show the existence of new physical phenomena, whether from a particle physics or an astrophysical origin."
