Taking The Plunge: Cassini Soars By Enceladus Pasadena CA (SPX) Nov 02, 2009
After so many close flybys of Enceladus, we're starting to feel as if this little moon of Saturn is an old friend. But during the encounter planned for Nov. 2, 2009, we are going to get up-close and personal. Cassini is going to take its deepest dive yet into the plumes spewing out from the moon's south pole to try to learn more about their composition and density. The spacecraft is going ... read moreRosetta's Third Earth Swingby
Paris, France (ESA) Nov 02, 2009On 13 November 2009 Rosetta will swing by Earth and pass within 2500 km of Earth's surface. The manoeuvre is the fourth and last in a series of gravity assists and will provide the spacecraft with the required orbital boost to set course for the mission's final destination: comet 67P/Churyumov-Gerasimenko. Since its launch on 2 March 2004 Rosetta has made a long journey through the inner ... more

Exoplanet House Of Horrors
Washington DC (SPX) Nov 02, 2009Astronomers may be closer than ever to discovering a planet that's habitable like our own, but along the way they've discovered some very scary exoplanets - places where conditions are far too harsh for life as we know it to exist. We've rounded up some of the most frightening, deadly exoplanets, places that make even the scariest haunted house on Earth pale in comparison. ... more Masten Space Systems Qualifies For One Million Dollar Prize
Mojave CA (SPX) Nov 02, 2009Masten Space Systems successfully qualified for first place in Level Two of the Northrop Grumman Lunar Lander Challenge Wednesday. Flying a brand new vehicle named XA-0.1E (nicknamed Xoie), Masten demonstrated their ability to build, debug and fly a vehicle on a very short timeline. "To come from not flying at all last year to qualifying for level one AND level two of the LLC this year ... more Mega-star explosion most distant object ever seen
Paris (AFP) Oct 29, 2009It took 13 billion years to reach Earth, but astronomers have seen the light of an exploding mega-star that is the most distant object ever detected, two studies published Thursday reported. The stunning gamma-ray burst (GRB) was observed by two teams of researchers in April, and opens a window onto a poorly known period when the Universe was in its infancy. GRBs are the most violent ... more |

Blast From The Past Gives Clues About Early Universe
Charlottesville VA (SPX) Oct 29, 2009Astronomers using the National Science Foundation's Very Large Array (VLA) radio telescope have gained tantalizing insights into the nature of the most distant object ever observed in the Universe - a gigantic stellar explosion known as a Gamma Ray Burst (GRB). The explosion was detected on April 23 by NASA's Swift satellite, and scientists soon realized that it was more than 13 billion ... more World's Fastest Supercomputer Models Origins Of The Unseen Universe
Los Alamos NM (SPX) Oct 28, 2009Understanding dark energy is the number one issue in explaining the universe, according to Salman Habib, of the Laboratory's Nuclear and Particle Physics, Astrophysics and Cosmology group. "Because the universe is expanding and at the same time accelerating, either there is a huge gap in our understanding of physics, or there is a strange new form of matter that dominates the universe ... more The Sun's Sneaky Variability
Huntsville AL (SPX) Oct 28, 2009Every 11 years, the sun undergoes a furious upheaval. Dark sunspots burst forth from beneath the sun's surface. Explosions as powerful as a billion atomic bombs spark intense flares of high-energy radiation. Clouds of gas big enough to swallow planets break away from the sun and billow into space. It's a flamboyant display of stellar power. So why can't we see any of it? Almost none ... more |
