Galaxy Evolution Explorer

The Galaxy Evolution Explorer (GALEX) was a space telescope launched by NASA in 2003 to study the universe in ultraviolet light. Its main goal was to observe how galaxies evolve over billions of years, helping scientists understand their formation and development. GALEX provided valuable insights into star formation, the life cycle of stars, and the relationships between different galaxies. By mapping the distribution and composition of galaxies, it enhanced our knowledge of the universe's history and the processes shaping it. GALEX completed its mission in 2012, leaving behind a legacy of important astronomical discoveries.
