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.
Along with the Hubble Space Telescope and now-retired Spitzer Space Telescope and Compton Gamma Ray Observatory, Chandra is one of NASA’s “Great Observatories” launched near the turn of the ...
[3] [7] The afterglow light emitted soon after the burst was found to be tera-electron volt radiation from inverse Compton emission, identified for the first time. [8] According to the astronomers, "We observed a huge range of frequencies in the electromagnetic radiation afterglow of GRB 190114C. It is the most extensive to date for a gamma-ray ...
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 ...
Gamma-ray telescopes collect and measure individual, high energy gamma rays from astrophysical sources. These are absorbed by the atmosphere, requiring that observations are done by high-altitude balloons or space missions. Gamma rays can be generated by supernovae, neutron stars, pulsars and black holes.
The Compton Spectrometer and Imager (COSI) is a NASA SMEX astrophysics mission that will launch a soft gamma-ray telescope (0.2–5 MeV) in 2027. [ 2 ] [ 3 ] It is a wide-field compact Compton telescope (CCT) that is uniquely suited to investigate the "MeV gap" (0.1–10 MeV). [ 4 ]
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 ...
