CGRO
- Compton Gamma-Ray Observatory
CGRO (Compton Gamma-Ray Observatory), one of NASAs 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 Ways distribution of a radioactive isotope of aluminum, and hinted at gamma-ray bursts cosmological origins, among other discoveries.
