NASA's Ames Research Center News and Features 29 Sep 2009, 04:00 UTC NASA's Lunar Crater Observation and Sensing Satellite mission (LCROSS) based on new analysis of available lunar data, has shifted the target crater from Cabeus A to Cabeus (proper).
ASI Agenzia Spaziale Italiana 28 Sep 2009, 09:49 UTC Andromeda is certainly one of the most photographed celestial objects, being the largest and nearest galaxy to our own Milky Way. Nobody, however, has seen it quite like this before. NASA’s Swift satellite, in its tireless pursuit of cosmic explosions, has taken a sensational image of Andromeda in all its ultraviolet beauty. The picture is commendable because it is the sharpest high resolution image in this wavelength of M31, as Andromeda is frequently known due to its position at number 31 in Charles Messier’s famous catalogue. “Swift has revealed about 20 thousand ultraviolet sources in M31, especially hot young stars and dense star clusters,” said Stefan Immer, scientist at NASA’s Goddard Space Flight Center. “The fact that we have mapped the galaxy with three ultraviolet filters is particularly significant. This has allowed us to study the stellar formation processes in M31 in greater detail than in the past.” M31 is two and a half million light years away (i.e. the distance that light takes two and a half million years to travel); it spreads across 220 thousand light years and contains hundreds of billions of stars. On a clear night, it is visible with the naked eye and is the ...
ESO Top News 28 Sep 2009, 07:00 UTC ESO 36/09 - Photo Release:The third image of ESO's GigaGalaxy Zoom project has just been released online, completing this eye-opening dive into our galactic home in outstanding fashion. The latest image follows on from views, released over the last two weeks, of the sky as seen with the unaided eye and through an amateur telescope. This third instalment provides another breathtaking vista of an astronomical object, this time a 370-million-pixel view of the Lagoon Nebula of the quality and depth needed by professional astronomers in their quest to understand our Universe.
NASA's Jet Propulsion Laboratory News and Features 24 Sep 2009, 19:09 UTC NASA scientists have discovered water molecules in the polar regions of the moon. Instruments aboard three separate spacecraft revealed water molecules in amounts that are greater than predicted, but still relatively small.
Keck Observatory 24 Sep 2009, 18:00 UTC KAMUELA, Hawaii (Sept. 24, 2009) — Linking the twin, 10-meter telescopes in Hawaii, astronomers at the W. M. Keck Observatory discovered an extended, double-layered dust disk orbiting 51 Ophiuchi, a star that is 410 light-years from Earth. It is the first time the Keck Interferometer Nuller instrument has identified such a compact cloud around a star so far away. The new data suggest that 51 Ophiuchi is a protoplanetary system with a dust cloud that orbits extremely close to its parent star, said University of Maryland astronomer Christopher Stark, who led the research team. Keck Observatory operates one of the…
NASA's Jet Propulsion Laboratory News and Features 23 Sep 2009, 19:09 UTC Astronomers have witnessed odd behavior around a young star. Something, perhaps another star or a planet, appears to be pushing a clump of planet-forming material around.
ASTRON 23 Sep 2009, 12:26 UTC An international group of astronomers have succeeded in the first joint observations between the LOFAR stations in Exloo (The Netherlands) and Effelsberg (Germany). This constitutes the "first light" of the LOFAR telescope as an international array. The bright quasar 3C 196, located almost ten billion light years away from Earth, was detected successfully on 2009 August 20 providing first "interferometric fringes", equivalent to the "first light" for an ordinary telescope.
ESO Top News 23 Sep 2009, 11:00 UTC ESO 35/09 - Organisational Release:The ALMA (Atacama Large Millimeter/submillimeter Array) astronomical observatory has taken another step forward - and upwards. One of its state-of-the-art antennas was carried for the first time to the 5000m plateau of Chajnantor, in the Chilean Andes, on the back of a custom-built giant transporter. The antenna, which weighs about 100 tons and has a diameter of 12 metres, was transported up to the high-altitude Array Operations Site, where the extremely dry and rarefied air is ideal for ALMA.s observations of the Universe.
