Gamma-ray view of the sky
This view of the gamma-ray sky is constructed from one year of Fermi Large Area Telescope (LAT) observations. The blue color includes the extragalactic gamma-ray background. The map shows the rate at which the LAT detects gamma rays with energies above 300 million electron volts – about 120 million times the energy of visible light – from different sky directions. Brighter colors represent higher rates.
