Extreme Ultraviolet Explorer (EUVE)

Extreme Ultraviolet Explorer

Extreme Ultraviolet Explorer (EUVE) is a NASA mission to study the universe as it appears in short-wavelength ultraviolet (UV) light. EUVE carried out an all-sky survey in the 7–76 nanometers (nm) portion of the spectrum and a "deep survey" of a strip of the sky along the ecliptic with extremely high sensitivity. It performed follow-up spectroscopic observations on bright extreme ultraviolet (EUV) point sources. Its results have been used to study stellar evolution and local stellar populations, energy transport in stellar atmospheres, and the ionization and opacity of the interstellar medium. At the end of the all-sky survey in January 1993, a Guest Observer program was started. EUVE was controlled from the Center for EUV Astrophysics at the University of California, Berkeley, and designed for on-orbit servicing by the Shuttle. Its main instruments were three grazing-incidence UV telescopes covering 8–90 nanometers and one EUV spectrometer.
