The Compton Gamma Ray Observatory (CGRO) is a artificial satellite that NASA launched into Earth orbit aboard the space shuttle Atlantis in 1991. The CGRO can be compared to the Hubble Space Telescope and other such space observatories such as the Chandra X-ray observatory. Therefor, no the observatory is not manned but rather controlled by ground personnel. After loosing one of its gyroscopes (used to maintain altitude and orientation) NASA decided that it would be in the best interest for the inhabitants of planet Earth (for safety reasons) to de-orbit the CGRO. On the 4th of June 2000, the CGRO burned up over the Pacific Ocean in a controlled reentry procedure.
Like the name suggest, the Compton Gamma Ray Observatory detects gamma rays.
196 million dollars.
There are four: Hubble Space Telescope, Compton Gamma Ray Observatory, Chandra X-ray Observatory, and the Spitzer Space Telescope.

Compton Scattering, Photoelectric Effect, and Pair Production.
It showed that most gamma ray bursts come from other galaxies, not our own. This means that gamma ray bursts must be extremely powerful.
Compton Scattering, Photoelectric Effect, and Pair Production.
they use gamma rays... i think. top that peeps!
The increase in wavelength of electromagnetic radiation, especially of an x-ray or a gamma-ray photon, scattered by an electron.
Photoelectric Effect, Compton Effect, and Pair Production.
One of the 7 types of of light. Gamma-rays have the smallest wavelengths and the most energy of any other wave in the electromagnetic spectrum. These waves are generated by radioactive atoms and in nuclear explosions. Gamma-rays can kill living cells, a fact which medicine uses to its advantage, using gamma-rays to kill cancerous cells. Gamma-rays travel to us across vast distances of the universe, only to be absorbed by the Earth's atmosphere. Different wavelengths of light penetrate the Earth's atmosphere to different depths. Instruments aboard high-altitude balloons and satellites like the Compton Observatory provide our only view of the gamma-ray sky.
