See the UltraViolet sky with GALEX. Learn about how galaxies form and evolve.
The Galaxy Evolution Explorer (GALEX) is an orbiting space telescope that will observe galaxies in ultraviolet light across 10 billion years of cosmic history. Such observations will tell scientists how galaxies, the basic structures of our Universe, evolve and change. Additionally, GALEX will probe the causes of star formation during a fperiod when most of the stars and elements we see today had their origins.
