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.
Compton Gamma Ray Observatory (CGRO) NASA: 5 Apr 1991: 4 Jun 2000: Earth orbit (362–457 km) [16] [17] [18] Low Energy Gamma Ray Imager (LEGRI) INTA: 19 May 1997 ...
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.
During its High Energy Astronomy Observatory program in 1977, NASA announced plans to build a "great observatory" for gamma-ray astronomy. The Compton Gamma Ray Observatory (CGRO) was designed to take advantage of the major advances in detector technology during the 1980s, and was launched in 1991. The satellite carried four major instruments ...
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]
The brightest gamma ray burst ever detected recently reached our planet. It’s 70 times longer than any other burst we’ve spotted, and effectively blinded our instruments when it hit ...
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.
