Gamma-ray astronomy is the study of high-energy radiation emitted by cosmic sources. This type of radiation, known as gamma rays, has the shortest wavelength and highest energy in the electromagnetic spectrum. Astronomers use specialized instruments, such as gamma-ray telescopes, to detect and analyze these rays, which can reveal information about extreme events in the universe, like supernovae and black hole activity. Gamma-ray astronomy helps scientists understand the processes occurring in the universe, including the formation of elements and the behavior of dark matter. By observing gamma rays, researchers can gain insights into the most energetic and violent phenomena, enhancing our knowledge of the cosmos.
