The Astrobiology Universe Moffett Field CA (SPX) Apr 30, 2008 
The opening speaker at the 2008 Astrobiology Science Conference, Lord Martin Rees of the University of Cambridge, said that our universe may just be one of many. Multiple universes could be stacked sideways like sheets of paper, separated by only a thin margin of space. We would never know they were there unless we could be awakened to the existence of that other dimension. This could have ... read more |

Stellar Ticking Time Bomb Explodes On Cue
Greenbelt MD (SPX) May 02, 2008Using observations from NASA's Rossi X-ray Timing Explorer, an international team of astronomers has discovered a timing mechanism that allows them to predict exactly when a superdense star will unleash incredibly powerful explosions. "We found a clock that ticks slower and slower, and when it slows down too much, boom! The bomb explodes," says lead author Diego Altamirano of the Universi ... more Oldest Known Objects Are Surprisingly Immature 
Boston MA (SPX) Apr 30, 2008Some of the oldest objects in the Universe may still have a long way to go, according to a new study using NASA's Chandra X-ray Observatory. These new results indicate that globular clusters might be surprisingly less mature in their development than previously thought. Globular clusters, dense bunches of up to millions of stars found in all galaxies, are among the oldest known objects in ... more Mcdonald Observatory Astronomers Discover New Type Of Pulsating White Dwarf Star 
Austin TX (SPX) May 02, 2008University of Texas at Austin astronomers Michael H. Montgomery and Kurtis A. Williams, along with graduate student Steven DeGennaro, have predicted and confirmed the existence of a new type of variable star with the help of the 2.1-meter Otto Struve Telescope at McDonald Observatory. The discovery will be announced in today's issue of Astrophysical Journal Letters. Called a "pulsating car ... more Hubble trouble: shuttle mission pushed back 
Washington (AFP) May 1, 2008The space shuttle's pending upcoming mission to continue maintenance and repair work on the Hubble telescope, which had been set for August 28, will be pushed back four to five weeks, NASA said Thursday. "Right now Hubble's mission is scheduled for August 28; we really cannot make that date with the external tank processing," shuttle program manager John Shannon explained at a press confere ... more Scientists Find Rings Of Jupiter Are Shaped In Shadow 
College Park MD (SPX) May 02, 2008Scientists from the University of Maryland and the Max-Planck Institute for Solar System Research in Germany appear to have solved a long-standing mystery about the cause of anomalies in Jupiter's gossamer rings. They report that a faint extension of the outermost ring beyond the orbit of Jupiter's moon Thebe, and other observed deviations from an accepted model of ring formation, result from th ... more |

Erie PA (SPX) Apr 25, 2008Astronomers are looking to identify Earth-like watery worlds circling distant stars from a glint of light seen through an optical space telescope and a mathematical method developed by researchers at Penn State and the University of Hawaii. "We are looking for Earth-like planets in the habitable zone of their star, a band not too hot nor too cold for life to exist," says Darren M. Williams ... more KAGUYA Captures First Successful Shooting Of A Full Earth-Rise 
Tokyo, Japan (SPX) Apr 23, 2008The Japan Aerospace Exploration Agency (JAXA) and NHK (Japan Broadcasting Corporation) successfully captured a movie of the "Full Earth-Rise"*1 using the onboard High Definition Television (HDTV) of the lunar explorer "KAGUYA " (SELENE) on April 6, 2008 (Japan Standard Time, JST, all the following dates and time are JST.) The KAGUYA is currently flying in a lunar orbit at an altitude of about 10 ... more NASA Spacecraft Tracks Raging Saturn Storm 
Pasadena CA (SPX) Apr 30, 2008As a powerful electrical storm rages on Saturn with lightning bolts 10,000 times more powerful than those found on Earth, the Cassini spacecraft continues its five-month watch over the dramatic events. Scientists with NASA's Cassini-Huygens mission have been tracking the visibly bright, lightning-generating storm--the longest continually observed electrical storm ever monitored by Cassini. ... more Black Hole Expelled From Its Parent Galaxy 
Garching, Germany (SPX) Apr 30, 2008By an enormous burst of gravitational waves that accompanies the merger of two black holes the newly formed black hole was ejected from its galaxy. This extreme ejection event, which had been predicted by theorists, has now been observed in nature for the first time. The team led by Stefanie Komossa from the Max Planck Institute for extraterrestrial Physics (MPE) thereby opened a new window in ... more |

Washington DC (SPX) Apr 28, 2008Let's do a little science experiment. If you have a can of whipped cream in the fridge, go get it out. Spray a generous dollop into a spoon and watch carefully. Notice anything interesting? The whipped cream just did something rather puzzling. First it flowed smoothly out of the nozzle like a liquid would, and then, a moment later, it perched rigidly in the spoon as if it were solid. What made ... more Exo-Planet Roadmap Advisory Team Appointed By ESA 
Paris, France (ESA) Apr 28, 2008An expert advisory team has been appointed by ESA with the purpose of advising the Agency on the best scientific and technological roadmap to pursue in order to address one of the most exciting goals in modern astrophysics: the characterization of terrestrial exo-planets (up to the possible detection of biomarkers). The Exo-Planet Roadmap Advisory Team (EPR-AT) will consult with the scient ... more Galaxies Gone Wild 
Washington DC (SPX) Apr 25, 2008Fifty nine new images of colliding galaxies make up the largest collection of Hubble images ever released together. As this astonishing Hubble atlas of interacting galaxies illustrates, galaxy collisions produce a remarkable variety of intricate structures. Interacting galaxies are found throughout the Universe, sometimes as dramatic collisions that trigger bursts of star formation, on oth ... more GLOBE At Night 2008 Results A Solid Step Toward IYA 2009 
Washington DC (SPX) Apr 25, 2008The international star-hunting activity known as GLOBE at Night inspired 6,838 measurements of night-sky brightness by citizen scientists around the world, including 660 digital measurements using handheld sky-quality meters. The third edition of GLOBE at Night was held from February 25-March 8, with assistance from the educational outreach networks of the Astronomical Society of the Pacif ... more
