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
CGRO (Compton Gamma-Ray Observatory), one of NASA's Great Observatories, studied the gamma-ray sky using four telescopes that detected different energies. The mission found a class of active galaxies called blazars, mapped the Milky Way’s distribution of a radioactive isotope of aluminum, and hinted at gamma-ray bursts’ cosmological origins ...
Over its nine-year lifetime, Compton produced the first-ever all-sky survey in gamma rays, the most energetic and penetrating form of light, discovered hundreds of new sources and unveiled a universe that was unexpectedly dynamic and diverse.
The Compton Gamma Ray Observatory (GRO) was a sophisticated satellite observatory dedicated to observing the high-energy Universe. It was the second in NASA ’s program of orbiting “Great Observatories”, following the Hubble Space Telescope.

The Spitzer Space Telescope is going on 13 years of infrared observations. The Chandra X-ray Observatory, launched in 1999 by the Space Shuttle Columbia, is still looking at X-rays. And then there is the Compton Gamma Ray Observatory (CGRO), which also just passed the 25th anniversary of its launch.
The Compton Gamma-Ray Observatory (CGRO) was launched on April 5, 1991. The second of NASA’s great observatories, CGRO has four instruments that cover an unprecedented six orders of magnitude in energy, from 30 keV to 30 GeV.
The Compton Gamma Ray Observatory was the second of NASA's Great Observatories. Compton, at 17 tons, was the heaviest astrophysical payload ever flown at the time of its launch on April 5, 1991 aboard the space shuttle Atlantis.
Over its nine-year lifetime, Compton produced the first-ever all-sky survey in gamma rays, the most energetic and penetrating form of light, discovered hundreds of new sources and unveiled a universe that was unexpectedly dynamic and diverse.
Twenty years ago, in a desolate stretch of the Pacific, 2,400 miles (3,900 kilometers) southeast of Hawaii, a spacecraft that opened our eyes to previously unseen cosmic sights, ended its mission...
