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.
NASA's Jet Propulsion Laboratory News and Features 22 Sep 2009, 19:09 UTC New, three-dimensional imaging of Martian north-polar ice layers by a radar instrument on NASA's Mars Reconnaissance Orbiter is consistent with theoretical models of Martian climate swings during the past few million years.
NASA's Chandra X-ray Observatory 22 Sep 2009, 17:00 UTC A dramatic new vista of the center of the Milky Way galaxy from Chandra X-ray Observatory exposes new levels of the complexity and intrigue in the Galactic center.
NASA's Jet Propulsion Laboratory News and Features 21 Sep 2009, 19:09 UTC NASA scientists are marveling over the extent of ruffles and dust clouds revealed in the rings of Saturn during the planet's equinox last month. Scientists once thought the rings were almost completely flat, but new images reveal the heights of some newly discovered bumps in the rings are as high as the Rocky Mountains. NASA released the images Monday.
