Galaxy Evolution Explorer
GALEX • Missions & Center • Past
The Galaxy Evolution Explorer (GALEX), launched on April 28th, 2003, is a NASA Small Explorer mission designed to provide broadband imaging and spectroscopy at ultraviolet wavelengths. GALEX's observations are being used to help explain how galaxies evolve and change, and to investigate the causes of star formation during a period when most of the stars and elements we see today had their origins. GALEX is conducting several first-of-a-kind sky surveys, including an extra-galactic ultraviolet all-sky survey. During its mission GALEX will produce the first comprehensive map of a Universe of galaxies under construction, bringing us closer to understanding how galaxies like our own Milky Way were formed.
On June 28, 2013 NASA announced the conclusion of the GALEX flight mission, after a decade of operations,
IPAC consulted in the development of the data processing system for GALEX.
