Socorro, NM (SPX) Feb 13, 2006
Astronomers studying a disk of material circling a still-forming star in the Milky Way have discovered the inner part of the disk is rotating in the opposite direction of the outer part of the disk. "Our data in conjunction with the data that other people have compiled show the two regions have velocity gradients that are opposite each other," Mike Hollis, a radio astrophysicist with NASA's Goddard Space Flight Center in Greenbelt, Md., told SpaceDaily.com.
Integral Looks At Earth To Seek Source Of Cosmic Radiation Paris, France (SPX) Feb 13, 2006
Cosmic space is filled with continuous, diffuse high-energy radiation. To find out how this energy is produced, the scientists behind ESA's Integral gamma-ray observatory have tried an unusual method: observing Earth from space.
Theft Of A Million Stars Cerro Paranal, Chile (SPX) Feb 13, 2006
Using ESO's Very Large Telescope, a team of Italian astronomers reveal the troubled past of the stellar cluster Messier 12 – our Milky Way galaxy 'stole' close to one million low-mass stars from it.
First Rave Data Release Offers Clues To Milky Way Evolution Aspen CO (SPX) Feb 13, 2006
An international team of astronomers released to the public the first data collected as part of the Radial Velocity Experiment, an ambitious spectroscopic survey aimed at measuring the speed, temperature, surface gravity and composition of up to a million stars passing near the sun.
New Antigravity Solution Could Enable Space Travel Near Speed Of Light San Diego CA (SPX) Feb 13, 2006
On Tuesday, Feb. 14, noted physicist Dr. Franklin Felber will present his new exact solution of Einstein's 90-year-old gravitational field equation to the Space Technology and Applications International Forum (STAIF) in Albuquerque. The solution is the first that accounts for masses moving near the speed of light.
Sounding Off In Deep Space Makes For An Explosive Supernova Tucson AZ (SPX) Feb 09, 2006 A powerful burst of sound resembling a musical note might be the final driving force between supernova explosions. New computer simulations suggest that dying stars tend to pulse at audible frequencies - at about the F-note above middle C on the piano -- for a split second before they blow up.
The Troubled Past Of Globular Cluster Messier 12 Cerro Paranal Chile (SPX) Feb 7, 2006 "In the solar neighborhood and in most stellar clusters, the least massive stars are the most common, and by far," said team leader Guido De Marchi. "Our observations with ESO's VLT show this is not the case for Messier 12."
Neutron Star Swaps Lead To Short Gamma-Ray Bursts Cambridge MA (SPX) Feb 01, 2006
Gamma-ray bursts are the most powerful explosions in the universe, emitting huge amounts of high-energy radiation. For decades their origin was a mystery. Scientists now believe they understand the processes that produce gamma-ray bursts.
Rogue Star Dangers Thought Slight Washington DC (SPX) Jan 31, 2006 Recent research showing there is a small population of hypervelocity stars streaking through the Milky Way doesn't mean there is much of a risk to humanity, either of a cataclysmic collision within the solar system or of significant gravitational disruptions.
Study Shows Most Milky Way Stars Are Single Red Dwarfs Cambridge, MA (SPX) Jan 30, 2006
New research shows that perhaps 60 billion stars in the Milky Way galaxy are single dim red dwarfs, not the bright, more visible stars seen in photos of the heavens, many of which travel with binary or multiple partners.
Two Exiled Stars Are Leaving Our Galaxy Forever Cambridge MA (SPX) Jan 27, 2006 TV reality show contestants aren't the only ones under threat of exile. Astronomers using the MMT Observatory in Arizona have discovered two stars exiled from the Milky Way galaxy. Those stars are racing out of the Galaxy at speeds of more than 1 million miles per hour - so fast that they will never return.
Dissecting Stardust Moffett Field CA (SPX) Jan 23, 2006
As they clustered around the Stardust sample return capsule, Donald Brownlee, Stardust principal investigator from the University of Washington in Seattle, warned his team they might not be able to see any comet dust. The tiny particles may have made such small tracks in the aerogel collector that they would not be visible to the naked eye.
