"Visualizing the Universe's Gamma Ray Brilliance"

NASA's Fermi Gamma-ray Space Telescope has compiled a catalog of 1,525 sources of gamma radiation, including blazars, pulsars, supernova remnants, and binary systems. The telescope constantly monitors the sky for gamma rays, the highest-energy light in the Universe, and provides astronomers with a map of the various producers of gamma radiation that we can detect. The newly updated catalog is freely available and could lead to new insights into past events and phenomena associated with gamma-ray sources.
