A nearby star is pummeling a companion planet with a barrage of X-rays 100,000 times more intense than the Earth receives from the sun. New data from NASA's Chandra X-ray Observatory and the European Southern Observatory's Very Large Telescope suggest that high-energy radiation is evaporating about 5 million tons of matter from the planet every second. This result gi

NASA will invite 25 of its U.S. Twitter followers to a Tweetup expected to culminate in the launch of the first of a new generation of Earth-observing satellites from Vandenberg Air Force Base (VAFB) in California. The event will take place from 9 a.m. to 5 p.m. PDT on Monday, Oct. 24. NASA's NPP satellite is scheduled to launch aboard a United Launch Alliance Delta
