Is There Anybody Out There Norwich, UK (SPX) Apr 18, 2008 
Is there anybody out there? Probably not, according to a scientist from the University of East Anglia. A mathematical model produced by Prof Andrew Watson suggests that the odds of finding new life on other Earth-like planets are low, given the time it has taken for beings such as humans to evolve and the remaining life span of Earth. Structurally complex and intelligent life evolved late ... read more |

The Moon And The Magnetotail
Huntsville AL (SPX) Apr 18, 2008Behold the full Moon. Ancient craters and frozen lava seas lie motionless under an airless sky of profound quiet. It's a slow-motion world where even a human footprint may last millions of years. Nothing ever seems to happen there. Right? Wrong. NASA-supported scientists have realized that something does happen every month when the Moon gets a lashing from Earth's magnetic tail. "Earth's ... more Stellar Birth In The Galactic Wilderness 
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 NASA official envisions six-month stays on the moon 
Miami (AFP) April 18, 2008NASA wants astronauts who will return to the moon to take one long step for mankind. The US space agency hopes to build moon bases that can house astronauts for stays of up to six months, with an intricate transportation and power system, Carl Walz, director of NASA's Advanced Capabilities Division, said Friday. NASA is examining different designs for lunar outposts but that they could b ... more Gravity Wave Smoking Gun Fizzles 
Cleveland OH (SPX) Apr 16, 2008A 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 ... 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 |

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 NASA Extends Cassini's Grand Tour Of Saturn 
Pasadena CA (SPX) Apr 16, 2008NASA is extending the international Cassini-Huygens mission by two years. The historic spacecraft's stunning discoveries and images have revolutionized our knowledge of Saturn and its moons. Cassini's mission originally had been scheduled to end in July 2008. The newly-announced two-year extension will include 60 additional orbits of Saturn and more flybys of its exotic moons. These will i ... 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 Moondust In The Wind 
Huntsville AL (SPX) Apr 14, 2008Moondust is dry, desiccated stuff, and may seem like a dull topic to write about. Indeed, you could search a ton of moondust without finding a single molecule of water, so it could make for a pretty "dry" story. But like the dust in your mother's attic, moondust covers something interesting - the moon - and even the dust itself has curious tales to tell. A group of NASA and University of ... more |

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 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 Old Galaxies Stick Together In The Young Universe 
Nottingham, UK (SPX) Apr 09, 2008Using the most sensitive images ever obtained with the United Kingdom Infra-Red Telescope (UKIRT), astronomers have found convincing evidence that galaxies which look old early in the history of the Universe reside in enormous clouds of invisible dark matter and will eventually evolve into the most massive galaxies that exist in the present day. University of Nottingham PhD student Will ... more
