Pulsars and supernova remnants, all bright gamma-ray sources for Fermi, also fleck the Milky Way band. Above and below the bright central plane, where our view of the broader cosmos becomes clearer, splotches of color brighten and fade. These sources are jets of particles moving at nearly the speed of light driven by supermassive black holes in distant galaxies. The jets happen to point almost directly toward Earth, which enhances their brightness and variability. Over a few days, these galaxies can erupt to become some of the brightest objects in the gamma-ray sky and then fade to obscurity. In these maps, brighter colors indicate more intense gamma-ray sources detected by Fermi’s Large Area Telescope from Aug. 10, 2008, to Aug. 2, 2022.Credit: NASA’s Goddard Space Flight Center and NASA/DOE/LAT Collaboration

Because this is an unusual view of the sky, the movies first overlay the stars and establish the locations of well- known constellations: Ursa Major (which includes the Big Dipper), Boötes, and Virgo in the northern galactic map; Cetus, Aries, and Pegasus in the southern galactic map. Notable gamma-ray sources include the sun (moving through the northern sky), the gamma-ray-only pulsar PSR J1836+5925 — a member of a new pulsar class discovered by Fermi — and numerous blazars (active galaxies).
