The Compton Gamma Ray Observatory (CGRO) was a space observatory detecting photons with energies from 20 keV to 30 GeV, in Earth orbit from 1991 to 2000. The observatory featured four main telescopes in one spacecraft, covering X-rays and gamma rays , including various specialized sub-instruments and detectors.
The Gamma Ray Observatory (GRO), renamed Compton Gamma-Ray Observatory (CGRO), was designed to take advantage of the major advances in detector technology during the 1980s. Following 14 years of effort, the CGRO was launched on 5 April 1991. [10] One of the three gyroscopes on the Compton Gamma Ray Observatory failed in December 1999. Although ...

In astrophysics, the most famous Compton telescopes was COMPTEL aboard the Compton Gamma Ray Observatory, which pioneered the observation of the gamma-ray sky in the energy range between 0.75 and 30 MeV. [3] [4] A potential successor is NCT – the Nuclear Compton Telescope.
STS-37, the thirty-ninth NASA Space Shuttle mission and the eighth flight of the Space Shuttle Atlantis, was a six-day mission with the primary objective of launching the Compton Gamma Ray Observatory (CGRO), the second of the Great Observatories program which included the visible-spectrum Hubble Space Telescope (HST), the Chandra X-ray ...
The Burst And Transient Source Experiment was a scientific instrument on the Compton Gamma-Ray Observatory (CGRO), and BACODINE monitored the BATSE real-time telemetry from CGRO. The first function of BACODINE was calculating the right ascension (RA) and declination (dec) locations for GRBs that it detected, and distributing those locations to ...
The sky as seen in high-energy gamma rays. The Energetic Gamma Ray Experiment Telescope (EGRET) was one of four instruments outfitted on NASA's Compton Gamma Ray Observatory satellite. Since lower energy gamma rays cannot be accurately detected on Earth's surface, EGRET was built to detect gamma rays while in space.
From 1991, the Compton Gamma Ray Observatory (CGRO) and its Burst and Transient Source Explorer instrument, an extremely sensitive gamma-ray detector, provided data that showed the distribution of GRBs is isotropic – not biased towards any particular direction in space. [23]
