a timely reality check |
 Bethesda MD (SPX) Jun 08, 2009 
The spacefaring nations of the world are coming to the conclusion that the space debris issue has evolved from a minor nuisance to a full-blown imperative. Hundreds, if not thousands, of decision makers, engineers, managers, politicians and policy makers have focused their attention on how to deal with the fast-growing threat to operational satellites and future access to space. All that ... read more 
Paris, France (SPX) Jun 08, 2009Using ESO's Very Large Telescope, astronomers have obtained one of the sharpest views ever of the Arches Cluster - an extraordinary dense cluster of young stars near the supermassive black hole at the heart of the Milky Way. Despite the extreme conditions astronomers were surprised to find the same proportions of low- and high-mass young stars in the cluster as are found in more tranquil ... more

St. Thomas, VI (SPX) Jun 08, 2009The 10th anniversary of the Gruber International Prize Program, which began with the Cosmology Prize in 2000, will be celebrated in July. This year the Cosmology Prize will be awarded to Freedman, Kennicutt and Mould for their outstanding work on resolving the value of the Hubble constant, the key determinant for how fast the Universe is expanding. The recipients of the 2009 Cosmology ... more 
Atlanta GA (UPI) Jun 4, 2009 U.S. researchers are using a simulated data center to develop new methods to reduce the heat generated by large computer equipment. Georgia Institute of Technology scientists said about a third of the electricity consumed by large data centers doesn't power computer servers, but instead must be used to cool the servers, a demand that continues to increase as computer processing power grows. The ... more 
Bethesda MD (SPX) Jun 03, 2009Every entrepreneur pursuing the space debris opportunity seems to have the single answer to removing space debris. It is cost-effective, simple, quick, safe, reliable, user-friendly, non-polluting, non-interfering and almost ready to go. There is simply nothing like it and it is wonderful. Why doesn't the government grab it up and make the entrepreneur rich? In fact, why doesn't the ... more  
Greenebelt MD (SPX) Jun 04, 2009As the closest planet to the sun, Mercury is scorching hot, with daytime temperatures of more than 800 degrees Fahrenheit (approximately 450 degrees Celsius). It is also the smallest rocky planet, so its gravity is weak, only about 38 percent of Earth's. These conditions make it hard for the planet to hold on to its atmosphere, which is extremely thin, and invisible to the human eye. Howev ... more |

Berkeley CA (SPX) May 29, 2009The chance discovery last month of a rare radio supernova - an exploding star seen only at radio wavelengths and undetected by optical or X-ray telescopes - underscores the promise of new, more sensitive radio surveys to find supernovas hidden by gas and dust. "This supernova is the nearest supernova in five years, yet is completely obscured in optical, ultraviolet and X-rays due to the ... more  
Pasadena CA (SPX) May 29, 2009A long-proposed tool for hunting planets has netted its first catch - a Jupiter-like planet orbiting one of the smallest stars known. The technique, called astrometry, was first attempted 50 years ago to search for planets outside our solar system, called exoplanets. It involves measuring the precise motions of a star on the sky as an unseen planet tugs the star back and forth. But the ... more 
Berkeley CA (SPX) May 29, 2009The joint Japan-U.S. Suzaku mission is providing new insight into how assemblages of thousands of galaxies pull themselves together. For the first time, Suzaku has detected X-ray-emitting gas at a cluster's outskirts, where a billion-year plunge to the center begins. "These Suzaku observations are exciting because we can finally see how these structures, the largest bound objects in the ... more  
Houston TX (SPX) May 29, 2009Take one space shuttle, seven highly trained astronauts, tons of equipment, and one legendary orbiting telescope and you have the 5.3 million-mile odyssey that was the final servicing mission for NASA's Hubble Space Telescope. After months of training and a seven-month postponement, the STS-125 crew's mission got under way with an on-time launch into a brilliant-blue Florida sky. The May ... more |
