NASA prepares to launch mission to study the sun
There is a mysterious area just above the sun’s surface called the interface region. This region, which is only 3,000 to 6,000 miles thick, is constantly experiencing movement of heat and energy. This energy helps heat the corona, the upper layer of the atmosphere, to temperatures of 1 million kelvins (approximately 1.8 million Fahrenheit). That makes this part of space nearly a thousand times hotter than the surface of the sun.
NASA’s IRIS Mission has been announced to study exactly how that energy travels through this area. IRIS stands for Interface Region Imaging Spectograph and is set to launch on June 26, 2013, from California’s Vandenberg Air Force Base…>>>more
