a timely reality check |
 Greenebelt MD (SPX) Jun 04, 2009 
As 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 ... read more 
Pasadena CA (SPX) Jun 04, 2009Cloud chasers studying Saturn's moon Titan say its clouds form and move much like those on Earth, but in a much slower, more lingering fashion. Their forecast for Titan's early autumn - warm and wetter. Scientists with NASA's Cassini mission have monitored Titan's atmosphere for three-and-a-half years, between July 2004 and December 2007, and observed more than 200 clouds. They found ... 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 govern ... more  
Moffett Field CA (SPX) Jun 02, 2009Four hundred years ago, the Italian scientist Galileo revolutionized the science of astronomy by inventing the first telescope. People began to consider the possibility of discovering other worlds like Earth - fantastic worlds inhabited by weird and wonderful civilizations. As technology continued to improve our telescopic vision, we sadly learned that the other planets in our solar system ... more  
London, UK (SPX) Jun 02, 2009Large bombardments of meteorites approximately four billion years ago could have helped to make the early Earth and Mars more habitable for life by modifying their atmospheres, suggests the results of a paper published in the journal Geochimica et Cosmochima Acta. When a meteorite enters a planet's atmosphere, extreme heat causes some of the minerals and organic matter on its outer crust ... more  
Warwick, UK (SPX) Jun 02, 2009While humans are still struggling to get rid of unwanted carbon it appears that the heavens are really rather good at it. New research by astrophysicists at the University of Warwick has discovered that a mystery stellar explosion recorded in 2006 may have marked the unusual death of an equally unusually carbon-rich star. The strange object known as SCP 06F6 was first noted in 2006 by ... more |

Moffett Field CA (SPX) May 29, 2009Although Captain Kirk and crew could zip over to a planet at warp speed and teleport down to the surface to check if it was inhabited, current-day scientists will generally have to search for life from a distance. New research gives This handedness, or homochirality, is characteristic of life on Earth. The molecules that make proteins and DNA all have either a left-handed or right-handed ... more  
Greenbelt MD (SPX) May 29, 2009Using data from NASA's THEMIS mission, a team of University of Alberta researchers has pinpointed the impact epicenter of an earthbound space storm as it crashes into the atmosphere, and given an advance warning of its arrival. The team's study reveals that magnetic blast waves can be used to pinpoint and predict the location where space storms dissipate their massive amounts of energy. ... more 
Greenbelt MD (SPX) May 29, 2009The instrument is in pieces now, but its legacy lives on. Twenty-one years ago this month, the balloon-borne Gamma-Ray Imaging Spectrometer (GRIS) made the first of nine trips into the stratosphere. Those voyages, totaling 223 hours of flight time, helped astronomers catch a glimpse of the high-energy universe. Satellites such as the European Space Agency's (ESA) International Gamma-Ray ... more  
Boston MA (SPX) May 29, 2009NASA's Chandra X-ray Observatory has found a cosmic "ghost" lurking around a distant supermassive black hole. This is the first detection of such a high-energy apparition, and scientists think it is evidence of a huge eruption produced by the black hole. This discovery presents astronomers with a valuable opportunity to observe phenomena that occurred when the Universe was very young. The ... more |
