The Extreme Ultraviolet Explorer (EUVE) was a space telescope for ultraviolet astronomy, launched on June 7, 1992. With instruments for ultraviolet (UV) radiation between wavelengths of 7 and 76 nm, the EUVE was the first satellite mission especially for the short-wave ultraviolet range. The satellite compiled an all-sky survey of 801 astronomical targets before being decommissioned on January 31, 2001. It re-entered the atmosphere on January 30, 2002. ==Mission goals== The goals of the mission included several different areas of observation using the extreme ultraviolet (EUV) range of frequencies: * To make an all-sky survey in the extreme ultraviolet band * To make a deep survey in the EUV range on two separate bandpasses * To make spectroscopic observations of targets found by other missions * To observe EUV sources such as hot white dwarfs and coronal stars * To study the composition of the interstellar medium using EUV spectroscopy * To determine whether it would be beneficial to create another, more sensitive EUV telescope 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Extreme Ultraviolet Explorer」の詳細全文を読む スポンサード リンク
