In reality, they are the sounds that accompany the aurora. Now ESA's Cluster mission is showing scientists how to understand this emission and, in the future, search for alien worlds by listening for their sounds.http://www.sciencedaily.com/releases/2008/06/080627163048.htm Cassini To Earth: 'Mission Accomplished, But New Questions Await!'- June 30, 2008 NASA's Cassini mission is closing one chapter of its journey at Saturn and embarking on a new one with a two-year mission that will address new questions and bring it closer to two of its most intriguing targets -- Titan and Enceladus.http://www.sciencedaily.com/releases/2008/06/080628223103.htm Phoenix Scrapes To Icy Soil In Wonderland- June 29, 2008 NASA's Phoenix Mars Lander scraped to icy soil in the "Wonderland" area on Thursday, June 26, confirming that surface soil, subsurface soil and icy soil can be sampled at a single trench.http://www.sciencedaily.com/releases/2008/06/080628222925.htm A Quark Star Super-luminous Stellar Explosion Observed- June 29, 2008 Astronomers recently announced that they have found a novel explanation for a rare type of super-luminous stellar explosion that may have produced a new type of object known as a quark star.http://www.sciencedaily.com/releases/2008/06/080628224224.htm Asteroid-hunting Satellite A World First- June 28, 2008 Canada is building the world's first space telescope designed to detect and track asteroids as well as satellites. Called NEOSSat, this spacecraft will provide a significant improvement in surveillance of asteroids that pose a collision hazard with Earth and innovative technologies for tracking satellites in orbit high above our planet.http://www.sciencedaily.com/releases/2008/06/080626125818.htm Phoenix Mars Lander Returns Treasure Trove For Science- June 27, 2008 NASA's Phoenix Mars Lander performed its first wet chemistry experiment on Martian soil flawlessly yesterday, returning a wealth of data that for Phoenix scientists was like winning the lottery.http://www.sciencedaily.com/releases/2008/06/080626214804.htm SOHO Discovers Its 1,500th Comet- June 27, 2008 The ESANASA SOHO spacecraft has just discovered its 1,500th comet, making it more successful than all other comet discoverers throughout history put together. Not bad for a spacecraft that was designed as a solar physics mission.http://www.sciencedaily.com/releases/2008/06/080627163117.htm If The Large Hadron Collider Produced A Microscopic Black Hole, It Probably Wouldn't Matter- June 27, 2008 Particle colliders creating black holes that could devour the Earth. Sounds like a great Hollywood script. But, according to UC Santa Barbara Physics Professor Steve Giddings, it's pure fiction. Giddings has co-authored a paper documenting his study of the safety of microscopic black holes that might possibly be produced by the Large Hadron Collider (LHC), which is nearing completion in Europe.http://www.sciencedaily.com/releases/2008/06/080627175348.htm Evidence Of Massive Asteroid Impact On Mars Supported By Computer Simulations- June 26, 2008 The dramatic differences between the northern and southern hemispheres of Mars have puzzled scientists for 30 years. One of the proposed explanations -- a massive asteroid impact -- now has strong support from computer simulations carried out by two groups of researchers.http://www.sciencedaily.com/releases/2008/06/080625140659.htm Largest Crater In Solar System Revealed By NASA Spacecraft- June 26, 2008 New analysis of Mars' terrain using NASA spacecraft observations reveals what appears to be by far the largest impact crater ever found in the solar system.http://www.sciencedaily.com/releases/2008/06/080625223036.htm |
