Galaxy Evolution Explorer Satellite (GALEX)

The Galaxy Evolution Explorer Satellite (GALEX) was a NASA mission led by the California Institute of Technology, whose primary goal was to investigate how star formation in galaxies evolved from the early universe up to the present. GALEX used microchannel plate detectors to obtain direct images in the near-UV (NUV) and far-UV (FUV), and a grism to disperse light for low resolution spectroscopy.

星系演化探测器卫星（Galaxy Evolution Explorer Satellite，GALEX）是一项由加州理工学院牵头的美国国家航空航天局（NASA）任务，其核心目标是探究星系内恒星形成过程自早期宇宙直至当代的演化历程。该探测器搭载微通道板探测器，用于获取近紫外（NUV）与远紫外（FUV）波段的直接成像数据，并通过棱栅（grism）对光线进行色散以开展低分辨率光谱学观测。
