Scientists are on the hunt for evidence of antimatter - matter's arch nemesis – left over from the very early Universe. New results using data from NASA's Chandra X-ray Observatory and Compton Gamma Ray Observatory suggest the search may have just become even more difficult.

A partnership between NASA and the U.S. Naval Academy is offering students real-world experience. During 2007 and 2008, students at the U.S. Naval Academy in Annapolis, Md., will build a satellite called "MidSTAR-2" through a U.S. Department of Defense program that will carry four experiments into space in 2011 to look at different parts of Earth's atmosphere, gamma rays and solar winds.
