星系演化探测器
Sign in to saveAlso known as GALEX, Explorer 83, SMEX-7, Small Explorer 7
Galaxy Evolution Explorer (GALEX or Explorer 83 or SMEX-7) was a NASA orbiting space telescope designed to observe the universe in ultraviolet wavelengths to measure the history of star formation in the universe. In addition to paving the way for future ultraviolet missions, the space telescope allowed astronomers to uncover mysteries about the early universe and how it evolved, as well as better characterize phenomena like black holes and dark matter. GALEX was launched on 28 April 2003 for a 29-month primary mission, which was extended three times before the spacecraft was placed into standb

星系演化探测器（Galaxy Evolution Explorer，缩写为GALEX）是美国宇航局2003年发射的一颗，主要目的是观测星系，特别是那些包含大量年轻恒星、辐射出强烈紫外线的星系，研究它们的形成和演化机制。这颗卫星是在2003年4月28日用飞马座火箭发射的，运行在高度697公里、倾角29度的近圆形轨道上，直径0.5米、焦距3米、重280公斤（620磅）、探测波长135-280nm（）。星系演化探测器耗资1.03亿美元，计划寿命为28个月，后延长至29个月。它观测从今回溯至大爆炸后80%时间（即最近100亿年）内的紫外线数据，确定星系和地球的距离，及各星系内恒星形成的规模。除美国宇航局喷气推进实验室外，加州理工学院、加州大学伯克利分校、约翰霍普金斯大学、韩国的延世大学、法国等大学和机构也参与了这颗卫星的研制。
