High energy astrophysics missions

NASA’s Structure and Evolution of the Universe (SEU) program uses X-ray and Gamma ray observations to observe the extremes of gravity throughout the universe. This program will probe the nature of black holes, ultimately obtaining a direct image of the event horizon. It will investigate the large scale structure of the Universe to constrain the location and nature of dark matter. Finally it will search for and study the highest energy processes, that approach those found in the early universe.
