UV astronomy is the study of celestial objects and phenomena using ultraviolet (UV) radiation. This branch of astronomy is important because UV light carries unique information about the physical conditions, chemical composition, and energetic processes in objects such as stars, galaxies, and quasars. UV astronomy allows scientists to study high-energy processes such as stellar nucleosynthesis, the formation of galaxies and black holes, and the interaction of cosmic rays with interstellar gas. Observations in the UV range are typically conducted using space-based telescopes as Earth's atmosphere blocks most UV radiation from reaching the surface. UV astronomy has provided important insights into the nature of the universe and continues to be a vital tool for astronomers seeking to understand the underlying physical processes that govern the cosmos.
