  1. X-Ray Astronomy • X-Rays • Light at high energies • Takes lots of energy to produce them • Atmosphere absorbs X-Rays • Most of the matter that we “see” is known to us from its X-Ray emission

  2. X-Ray Astronomy • Solar Studies in late 40’s • Discovery of first extra solar source in 1962 • Also discovery of faint glow (the “diffuse background)

  3. Project History • Began in 1976 • Launch in 1999
