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.
The Compton Gamma Ray Observatory was launched in 1991 and its cost was approximately $617 million.
The space shuttle Atlantis launched the Magellan and Galileo planetary probes, as well as the Compton Gamma Ray Observatory.
The Compton gamma-ray telescope detects high-energy gamma rays, which are a type of electromagnetic radiation with the shortest wavelengths and highest frequencies in the electromagnetic spectrum. These gamma rays are produced by astrophysical processes such as supernovae, pulsars, and black holes.
There are four: Hubble Space Telescope, Compton Gamma Ray Observatory, Chandra X-ray Observatory, and the Spitzer Space Telescope.
The Compton edge in gamma spectroscopy is significant because it represents the maximum energy that a photon can transfer to an electron during a Compton scattering event. This edge helps in determining the energy of gamma rays and can be used to identify the source of radiation.
Compton Scattering, Photoelectric Effect, and Pair Production.
The discovery of Compton scattering is the phenomenon where incoming gamma rays collide with electrons, resulting in a shift in the gamma ray's wavelength. This discovery helped confirm the wave-particle duality of light and demonstrated the particle nature of light.
The Compton continuum is important in nuclear physics because it represents the range of energies of gamma rays produced during Compton scattering. This phenomenon helps scientists study the interactions between gamma rays and matter, providing valuable insights into the structure of atomic nuclei and the behavior of subatomic particles.
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.
Five artificial satellites that are orbiting the earth are ACRIMSAT, HAMSAT, OSCAR 3, PicoSAT and RADARSAT. There are scores of satellites that orbit the Earth for one reason or another.
