The telescope made observations in ultraviolet wavelengths to measure the history of [[star]] formation in the [[universe]] 80% of the way back to the [[Big Bang]]. Since scientists have evidence that the Universe to be about 13.8 billion years old, the mission studied galaxies and stars across about 10 billion years of cosmic history.<ref>{{cite web |url=http://www.esa.int/Our_Activities/Space_Science/Cosmic_detectives|title=Cosmic Detectives|publisher=European Space Agency (ESA)|date=2013-04-02|access-date=2013-04-26}}</ref>

The [[space observatory|spacecraft's]] mission was to observe hundreds of thousands of galaxies, with the goal of determining the distance of each galaxy from [[Earth]] and the rate of [[star formation]] in each galaxy. Near-UV (NUV) and Far-UV (FUV) emissions as measured by GALEX can indicate the presence of young stars, but may also originate from old stellar populations (e.g. [[sdB stars]]).

Partnering with the NASA [[Jet Propulsion Laboratory]] (JPL) on the mission were the [[California Institute of Technology]], [[Orbital Sciences Corporation]], [[University of California, Berkeley]], [[Yonsei University]], [[Johns Hopkins University]], [[Columbia University]], and [[Marseille Observatory|Laboratoire d'Astrophysique de Marseille]], [[France]].

The observatory participated in GOALS with [[Spitzer Space Telescope]], [[Chandra X-ray Observatory]], and [[Hubble Space Telescope]].<ref name=goals>[https://arxiv.org/abs/0904.4498 GOALS: The Great Observatories All-Sky LIRG Survey]</ref> GOALS stands for ''Great Observatories All-sky LIRG Survey'', and [[Luminous Infrared Galaxies]] were studied at the multiple wavelengths allowed by the telescopes.<ref name=goals/>
