The Question

(Submitted December 18, 1996)

Hi, I was wondering what space astronomy was?

The Answer

Space Astronomy refers to the study of astronomical objects using instruments flown on satellites. These instruments may detect gamma-rays, x-rays, ultraviolet light, optical light or infrared. The Hubble Space Telescope, the Rossi X-ray Timing Explorer, and the Extreme Ultraviolet Explorer are examples of satellites used in the study of space astronomy. Space Astronomers study a wide range of objects, from normal stars to black holes to active galaxies.

As I'm sure you've noticed, our web site concentrates on x-rays and gamma-rays. It has more information about the objects we study and the satellites we use.
