Fermi has detected more than 1,000 gamma-ray sources. Half are associated with active galaxies called blazars. This movie shows one year of blazar activity, starting on Aug. 4, 2008, around the galactic north pole. This region includes the constellations Ursa Major, Virgo, Leo, Boötes, and Coma Berenices.
