ACTIVE GALAXIES

Observations using NASA's Extreme Ultraviolet Explorer (EUVE) satellite show that most active galaxies contain cold gas that obscures the view to the central engine that powers them, according to scientists at the Center for EUVE Astrophysics. Active galaxies emit unusually large amounts of energy from a very compact central source, thought to be a black hole.

EUV Radiation

This image taken by NASA's Extreme Ultraviolet Explorer (EUVE) shows two sources of extreme ultraviolet (EUV) radiation. The fainter image to the right is a star known only by its catalogue number HR 6094. The brighter image to the left is it companion star WD1620-391.

SPARTAN

Seen here between the Atlas-2 payload and the space shuttle aft firewall is the Goddard Space Flight Center's Spartan 201, flown aboard the Space Shuttle Discovery in April 1993. The Spartan 201 satelite was released from the cargo bay into a free-flying orbit, retrieved later and returned to Earth. In the background is an oblique view south of Korea.

CGRO

This image is the Compton Gamma Ray Observatory deployment in April, 1991.
