Satellite Showcase

The 40th Anniversary of X-ray Astronomy

The summer of 2002 marks the 40th anniversary of the birth of X-ray astronomy. We've come a long way since June 18, 1962, when the first X-ray object outside our solar system was discovered. Our understanding of the universe has grown as a string of X-ray satellites have revealed exotic objects and energetic events.

This Special Exhibit provides a retrospective of the history of X-ray astronomy, highlighting the contributions made through the use of satellite observatories.

Imagine the Universe is a service of the High Energy Astrophysics Science Archive Research Center (HEASARC), Dr. Alan Smale (Director), within the Astrophysics Science Division (ASD) at NASA's Goddard Space Flight Center.
