Herschel's HIFI Follows The Trail Of Cosmic WaterParis, France (ESA) May 11, 2010 Herschel's HIFI instrument was especially designed to follow the water trail in the Universe over a wide range of scales, from the Solar System out to extragalactic sources. Early results, presented this week at the Herschel First Results Symposium, demonstrate how HIFI uses water to probe the physical and chemical conditions in different regions of the cosmos. Water is an extremely important molecule in the Universe, abundant in a large variety of cosmic environments - from our own blue planet an ... read more |

Pasadena CA (JPL) Apr 30, 2010Near-Earth asteroid 2005 YU55 was "imaged" by the Arecibo Radar Telescope in Puerto Rico on April 19. Data collected during Arecibo's observation of 2005 YU55 allowed the Near-Earth Object Program Office at NASA's Jet Propulsion Laboratory to refine the space rock's orbit, allowing scientists to rule out any possibility of an Earth impact for the next 100 years. The space rock was about 2. ... more  
Greenbelt MD (SPX) Apr 30, 2010Sophisticated new technologies created by NASA and university scientists are enabling them to build an instrument designed to probe the first moments of the universe's existence. Former NASA scientist Chuck Bennett, now an astrophysicist at Johns Hopkins University (JHU) in Baltimore, Md., won a $5-million National Science Foundation grant to build a new ground-based instrument, the Cosmol ... more 
Paris, France (ESA) Apr 30, 2010New evidence from NASA's Chandra X-ray Observatory and ESA's XMM-Newton strengthens the case that two mid-sized black holes exist close to the center of a nearby starburst galaxy. These "survivor" black holes avoided falling into the center of the galaxy and could be examples of the seeds required for the growth of supermassive black holes in galaxies, including the one in the Milky Way.

Scientists Finds Evidence Of Water Ice On Asteroid's SurfaceKnoxville TN (SPX) Apr 29, 2010 Asteroids may not be the dark, dry, lifeless chunks of rock scientists have long thought. Josh Emery, research assistant professor with the earth and planetary sciences department at the University of Tennessee, Knoxville, has found evidence of water ice and organic material on the asteroid 24 Themis. This evidence supports the idea that asteroids could be responsible for bringing water and organic material to Earth. The findings are detailed in the journal "Nature." Using NASA's Infra ... read more |
