Compton Gamma Ray Observatory
The Compton Gamma Ray Observatory (CGRO) was a space telescope launched by NASA in 1991. It was designed to study gamma rays, the highest-energy form of electromagnetic radiation, which are produced by some of the most energetic and violent processes in the universe. CGRO operated until 2000 and significantly advanced our understanding of phenomena such as black holes, supernovae, and gamma-ray bursts.
CGRO was equipped with four scientific instruments that allowed it to detect and analyze gamma rays from various cosmic sources. Its findings contributed to the development of gamma-ray astronomy and provided valuable data for future missions, including the Fermi Gamma-ray Space Telescope.
