The Antennae Galaxies Found To Be Closer To Us Paris, France (ESA) May 12, 2008 
New research on the Antennae Galaxies using the Advanced Camera for Surveys onboard the NASA/ESA Hubble Space Telescope shows that this proto-typical pair of interacting galaxies is in fact much closer to us than previously thought - at 45 million light-years instead of 65 million light-years. The Antennae Galaxies are among the closest known merging galaxies. The merging pair of galaxies ... read more |

Argonne Supercomputer To Simulate Extreme Physics Of Exploding Stars
Chicago IL (SPX) May 05, 2008Robert Fisher and Cal Jordan are among a team of scientists who will expend 22 million computational hours during the next year on one of the world's most powerful supercomputers, simulating an event that takes less than five seconds. Fisher and Jordan require such resources in their field of extreme science. Their work at the University Of Chicago's center for astrophysical thermonuclear ... 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 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 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 Galaxy Evolution Explorer Celebrates Five Years In Space 
Pasadena CA (SPX) Apr 30, 2008Since its launch five years ago, the Galaxy Evolution Explorer has photographed hundreds of millions of galaxies in ultraviolet light. M106 is one of those galaxies, and from 22 light years away, it strikes a pose in blue and gold for this new commemorative portrait. The galaxy's extended arms are the blue filaments that curve around its edge, creating its outer disk. Tints of blue in M106 ... more |

Pasadena CA (SPX) Apr 18, 2008A new image from NASA's Galaxy Evolution Explorer shows baby stars sprouting in the backwoods of a galaxy -- a relatively desolate region of space more than 100,000 light-years from the galaxy's bustling center. The striking image, a composite of ultraviolet data from the Galaxy Evolution Explorer and radio data from the National Science Foundation's Very Large Array in New Mexico, shows the ... more Spitzer Sees Shining Stellar Sphere 
Los Angeles CA (SPX) Apr 15, 2008Millions of clustered stars glisten like an iridescent opal in a new image from NASA's Spitzer Space Telescope. Called Omega Centauri, this sparkling orb of stars is like a miniature galaxy. It is the biggest and brightest of the more than 150 similar objects, called globular clusters, that orbit around the outside of our Milky Way galaxy. Stargazers at southern latitudes can spot the stellar ge ... more The Coldest Brown Dwarf Ever Observed: Closing The Gap Between Stars And Planets 
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 Witnessing The Formation Of Distant Galaxies 
London, UK (SPX) Apr 09, 2008UK astronomers have produced the most sensitive infrared map of the distant Universe ever undertaken. Combining data over a period of three years, they have produced an image containing over 100,000 galaxies over an area four times the size of the full Moon. Some of the first results from this project will be presented by Dr Sebastien Foucaud from the University of Nottingham ... more Quasars Quash Star Formation In Active Galactic Nuclei 
London, UK (SPX) Apr 09, 2008An ambitious study of active and inactive galaxies has given new insights into the complex interaction between super-massive black holes at the heart of Active Galactic Nuclei (AGN) and star formation in the surrounding galaxy. Results will be presented in a talk by Paul Westoby at the RAS National Astronomy Meeting in Belfast. Along with colleagues, Carole Mundell and Ivan Baldry from ... more |

Irvine CA (SPX) Apr 03, 2008UC Irvine scientists have discovered a cluster of galaxies in a very early stage of formation that is 11.4 billion light years from Earth - the farthest of its kind ever to be detected. These galaxies are so distant that the universe was in its infancy when their light was emitted. The galaxy proto-cluster, named LBG-2377, is giving scientists an unprecedented look at galaxy formation and ... more Two New Star Systems Are First Of Their Kind Ever Found 
Columbus OH (SPX) Apr 02, 2008Astronomers have spied a faraway star system that is so unusual, it was one of a kind -- until its discovery helped them pinpoint a second one that was much closer to home. In a paper published in a recent issue of the Astrophysical Journal Letters, Ohio State University astronomers and their colleagues suggest that these star systems are the progenitors of a rare type of supernova. They ... more Mars, Earth And Moon From Unique Planetary Nursery 
Oxford, UK (SPX) Mar 28, 2008A study of meteorites suggests that Mars, the Earth and the Moon share a common composition from 'growing up' in a unique planetary nursery in the inner solar system. The finding could lead to a rethink of how the inner solar system formed. The international team of scientists, which includes Professor Alex Halliday from Oxford University's Department of Earth Sciences, report in Nature how they ... more Astronomers Coordinating International Observatories In White-Dwarf Watch 
Newark, DE (SPX) Mar 28, 2008Judi Provencal is star-struck, but not so much by the glitz and glam of Hollywood. You have to look heavenward through a telescope to see the object of her fascination--to pale stars called white dwarfs, their brilliance faded because all of their nuclear fuel has been burned up. A white dwarf is a star that is "dying," cooling down in the twilight of its life. It's what the sun will ... more Action Replay Of Powerful Stellar Explosion 
Boston MA (SPX) Mar 25, 2008Astronomers have made the best ever determination of the power of a supernova explosion that was visible from Earth long ago. By observing the remnant of a supernova and a light echo from the initial outburst, they have established the validity of a powerful new method for studying supernovas. Using data from NASA's Chandra X-ray Observatory, ESA's XMM-Newton Observatory, and the Gemini Ob ... more
