Gravity Wave Smoking Gun Fizzles Cleveland OH (SPX) Apr 16, 2008 
A team of researchers from Case Western Reserve University has found that gravitational radiation-widely expected to provide "smoking gun" proof for a theory of the early universe known as "inflation"-can be produced by another mechanism. According to physics scholars, inflation theory proposes that the universe underwent a period of exponential expansion right after the big bang. A key ... read more |

German whizzkid got it wrong: NASA
Washington (AFP) April 16, 2008It was an incredible tale of a German schoolboy spotting a miscalculation by the US space agency, proving the chances of an asteroid hitting the Earth were higher than initially believed. But the amazing story of the whizzkid versus the space bureaucracy turned out to be wrong, the National Aeronautics and Space Administration said Wednesday. The agency, sounding a bit like a weary math ... more Astronomers Listen To An Exoplanet-Host Star And Find Its Birthplace 
Paris, France (SPX) Apr 16, 2008By studying in great detail the 'ringing' of a planet-harbouring star, a team of astronomers using ESO's 3.6-m telescope have shown that it must have drifted away from the metal-rich Hyades cluster. This discovery has implications for theories of star and planet formation, and for the dynamics of our Milky Way. The yellow-orange star Iota Horologii, located 56 light-years away towards the ... more Confusion Over Asteroid Calculation Sorted As NASA Issues Clarification 
Pasadena CA (JPL) Apr 16, 2008A 13-year-old German schoolboy corrected NASA's estimates on the chances of an asteroid colliding with Earth, a German newspaper reported Tuesday, after spotting the boffins had miscalculated. Nico Marquardt used telescopic findings from the Institute of Astrophysics in Potsdam (AIP) to calculate that there was a 1 in 450 chance that the Apophis asteroid will collide with Earth, the Potsdame ... more Milky Way's Giant Black Hole Awoke From Slumber 300 Years Ago 
Greenbelt MD (SPX) Apr 16, 2008Using NASA, Japanese, and European X-ray satellites, a team of Japanese astronomers has discovered that our galaxy's central black hole let loose a powerful flare three centuries ago. The finding helps resolve a long-standing mystery: why is the Milky Way's black hole so quiescent? The black hole, known as Sagittarius A* (pronounced "A-star"), is a certified monster, containing about 4 million t ... more Intelligence: A Rare Cosmic Commodity 
Moffett Field CA (SPX) Apr 15, 2008Advanced ground and space-based telescopes are discovering new planets around other stars almost daily, but an environmental scientist from England believes that even if some of those planets turn out to be Earth-like, the odds are very low they'll have intelligent inhabitants. In a recent paper published in the journal Astrobiology, Professor Andrew Watson of the University of East Anglia descr ... more |

Washington DC (SPX) Apr 14, 2008An international team of astronomers has discovered the coldest brown dwarf star ever observed. This finding, to be published in Astronomy and Astrophysics, is a new step toward filling the gap between stars and planets. An international team led by French and Canadian astronomers has just discovered the coldest brown dwarf ever observed. Their results will soon be published in Astronomy a ... more New Rocky Planet Found In Constellation Leo 
London, UK (SPX) Apr 10, 2008Spanish and UCL (University College London) scientists have discovered a possible terrestrial-type planet orbiting a star in the constellation of Leo. The new planet, which lies at a distance of 30 light years from the Earth, has a mass five times that of our planet but is the smallest found to date. One full day on the new planet would be equivalent to three weeks on Earth. The team of as ... more RIT Team Simulates First Merger Of Three Black Holes On A Supercomputer 
Rochester NY (SPX) Apr 10, 2008The same team of astrophysicists that cracked the computer code simulating two black holes crashing and merging together has now, for the first time, caused a three-black-hole collision. Manuela Campanelli, Carlos Lousto and Yosef Zlochower-scientists in Rochester Institute of Technology's Center for Computational Relativity and Gravitation-simulated triplet black holes to test their break ... more NASA Sets Sights On Lunar Dust Exploration Mission 
Washington DC (SPX) Apr 10, 2008NASA is preparing to send a small spacecraft to the moon in 2011 to assess the lunar atmosphere and the nature of dust lofted above the surface. Called the Lunar Atmosphere and Dust Environment Explorer (LADEE), the mission will launch before the agency's moon exploration activities accelerate during the next decade. LADEE will gather detailed information about conditions near the surface ... more |

Huntsville AL (SPX) Apr 08, 2008Not one of the participants in NASA's 2008 Great Moonbuggy Race was old enough to have seen the 1969 movie, Those Daring Young Men in Their Jaunty Jalopies. Nevertheless, the racers all looked like stars of that film as they careened about the simulated lunar terrain race course in a motley variety of strange vehicles. These high school and college students, representing 20 states, Puerto ... more IU Asteroid Program Records Final Chapter 
Bloomington IN (SPX) Apr 08, 2008The Indiana Asteroid Program began with a borrowed lens and a bet over a chocolate ice cream cone. Almost 60 years later, its final chapter was written with the naming of a heavenly body after one of the most dedicated staff members Indiana University Bloomington's Department of Astronomy has ever seen. The program -- launched in 1949 by Hoosier astronomy legend Frank Edmondson -- aimed to ... more New Laser Technology Could Find First Earth-like Planets 
Cambridge MA (SPX) Apr 08, 2008The leading method of finding planets orbiting distant stars spots mostly Jupiter-sized worlds. Technology limitations make it difficult to detect smaller planets. But that is about to change. A revolutionary laser technology being developed by scientists and engineers at the Harvard-Smithsonian Center for Astrophysics (CfA), with colleagues at MIT, will enable scientists to spot Earth-sized ... more NASA Selects Three Research Fellows For GLAST Mission 
College Park MD (SPX) Apr 08, 2008After a nationwide search for junior science researchers on NASA's Gamma-ray Large Area Telescope (GLAST) mission, three people have been chosen for these prestigious post-doctoral positions. The purpose of the fellowship program is to support outstanding postdoctoral scientists who endeavor to advance understanding of the gamma-ray universe. The goal of the program is to stimulate an ... more
