Ultraviolet Space Telescopes

What was the EUVE satellite?

The Extreme Ultraviolet Explorer (EUVE) mission was the first telescope dedicated to observing the universe in the shortest wavelengths of ultraviolet light. This kind of ultraviolet radiation is almost as energetic as X-ray radiation, so EUVE was built using a combination of ultraviolet and X-ray telescope technology. It was launched on June 7, 1992, and operated until January 31, 2001. Among its scientific accomplishments were an all-sky survey catalog of 801 objects; the first extreme ultraviolet detections of objects outside the Milky Way galaxy; the detection of extreme UV photospheric emission from stars; and observation of particular behaviors of unusual objects, such as quasi-periodic oscillations in a dwarf nova.
