GALEX stands for Galaxy Evolution Explorer

GALEX, or Galaxy Evolution Explorer, is a NASA space mission designed to study the formation and evolution of galaxies. Launched in 2003, GALEX utilized ultraviolet observations to investigate the processes that influence star formation and galaxy growth over cosmic time. By capturing detailed images and spectral data, GALEX contributed significantly to our understanding of the universe's structure and the lifecycle of galaxies, enhancing knowledge of how galaxies evolve from their early stages to the present day.
