The Galaxy Evolution Explorer was an 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. The mission was extended three times over a period of 10 years before it was decommissioned in June 2013.
