ESA Space Science 12 Nov 2009, 15:38 UTC This spectacular image of our home planet was captured by the OSIRIS instrument on ESA's Rosetta comet chaser earlier today as the spacecraft approached Earth for the third and final swingby. Closest approach is due at 08:45 CET, 13 November 2009. Follow Rosetta's progress at ESA's dedicated Rosetta site and via the Rosetta Blog.
ESA Top News 12 Nov 2009, 12:45 UTC When Europe's comet chaser Rosetta swings by Earth tomorrow for a critical gravity assist, tracking data will be collected to precisely measure the satellite's change in orbital energy. The results could help unravel a cosmic mystery that has stumped scientists for two decades.
NASA's Jet Propulsion Laboratory News and Features 11 Nov 2009, 20:11 UTC Engineers are busy cooling the science instrument on NASA's Wide-field Infrared Survey Explorer, or WISE.
ESO Top News 11 Nov 2009, 18:00 UTC A ground-breaking census of 500 stars, 70 of which are known to host planets, has successfully linked the long-standing "lithium mystery" observed in the Sun to the presence of planetary systems. Using ESO's successful HARPS spectrograph, a team of astronomers has found that Sun-like stars that host planets have destroyed their lithium much more efficiently than "planet-free" stars. This finding does not only shed light on the lack of lithium in our star, but also provides astronomers with a very efficient way of finding stars with planetary systems.
ESA Top News 11 Nov 2009, 08:10 UTC ESA’s ‘Fly Your Thesis!’ programme made its successful debut during ESA’s 51st Parabolic Flight Campaign, held 25 October to 5 November. Four student teams from five European countries took advantage of this new educational initiative to conduct microgravity experiments on the Airbus A300 ‘Zero G’ aircraft.
Royal Astronomical Society 11 Nov 2009, 00:13 UTC The Universe’s infant galaxies enjoyed rapid growth spurts forming stars like our Sun at a rate of up to 50 stars a year, according to scientists at Durham University. Led by RAS Norman Lockyer Fellow Dr Mark Swinbank, the team's work appears in Monthly Notices of the Royal Astronomical Society. (Image credit: Dr Johan Richard, Durham University)
NASA's Chandra X-ray Observatory 10 Nov 2009, 17:00 UTC In this spectacular image, observations using infrared light and X-ray light see through the obscuring dust and reveal the intense activity near the galactic core.
Keck Observatory 10 Nov 2009, 03:51 UTC BERKELEY, CA—An unusual supernova rediscovered in seven-year-old data taken at the W. M. Keck Observatory and Lick Observatory may be the first example of a new type of exploding star, possibly in a binary star system where helium flows from one white dwarf onto another and detonates in a thermonuclear explosion. In a paper first published online Nov. 5 in Science Express, astronomer Dovi Poznanski, of the University of California, Berkeley (UCB) and Lawrence Berkeley National Laboratory (LBNL), and his colleagues describe supernovae SN 2002bj and review the data that suggest it is a new type of stellar explosion.
