Allows astronomers to study stars, planets, galaxies and observe their color, which indicates temperature and composition.
Ultraviolet (UV)
Provides insight into very hot objects, such as young stars, and phenomena like auroras and the interstellar medium.
X-rays
Useful for studying high-energy objects and environments such as neutron stars, black holes, and supernova remnants.
Gamma Rays
Important for studying cosmic events like supernovae and gamma-ray bursts, and tracking radioactive decay in the universe.
Radio Waves
Astronomers can study the structure and composition of galaxies, nebulae, and other cosmic phenomena.
