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.
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 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.
Space debris from rocket bodies orbiting Earth is posing an increased threat to aircraft while falling from space, according to new research. While the probability of space junk striking an ...
In the dark hours of the morning of January 23, 1999, the Compton satellite recorded a gamma-ray burst that lasted for about a minute and a half. There was a peak of gamma and X-ray emission 25 seconds after the event was first detected, followed by a somewhat smaller peak 40 seconds after the beginning of the event.
The Chandra X-ray Observatory marked its 25th anniversary with a release of never-before-seen images. But budget cuts may cause the observatory’s days to be numbered.
The brightest gamma ray burst ever detected recently reached Earth. It’s 70 times longer than any other burst we’ve spotted.
