Gamma Ray Sky Map


This all-sky image made in 2011 was constructed using two years of observations by NASA's Fermi Gamma-ray Space Telescope. It shows how the sky appears at energies greater than 1 billion electron volts (1 GeV). Brighter colors indicate brighter gamma-ray sources. A diffuse glow fills the sky and is brightest along the plane of our galaxy (middle). Discrete gamma-ray sources include pulsars and supernova remnants within our galaxy, as well as distant galaxies powered by supermassive black holes.
