Exoplanet Science Strategy September 21, 2018. NASA - NSSDCA - Spacecraft - Details Description The Compton Gamma-Ray Observatory (GRO) is one of NASA's four "Great Observatories". It mapped hundreds of gamma ray sources and recorded more than 2,500 gamma ray bursts, signs of the most violent happenings in the Universe. It featured four main telescopes in one spacecraft covering x-rays and gamma-rays, including various specialized sub-instruments and detectors. Astronomers were so ecited by the initial results, it wasn't long before discussions . Compton Gamma Ray Observatory From Wikipedia, the free encyclopedia . discovery. Compton recorded more than 2,500 gamma ray bursts; before Compton, only about 300 had been detected. Since we found new sources all over the sky, there were many questions raised by the CGRO discoveries. The Compton Gamma-ray Observatory was launched on April 5, 1991 and had its last day of operation in 2000. Ryan , I.
