Mission Basics-

With sensitive ultraviolet detectors, a large field of view, and its location above the ultraviolet-absorbing atmosphere of the Earth, GALEX will perform ground breaking observations of the ultraviolet sky. GALEX will detect ultraviolet objects in the sky that are more than a million times fainter than objects we can see in visible light with our eyes from the darkest location on the ground. GALEX will also peer billions of years back into the history of the Universe.
