Fermi's 12-year View of the Gamma-ray Sky

These all-sky view shows how the sky appears at energies greater than 1 billion electron volts (GeV) according to 12 years of data from NASA's Fermi Gamma-ray Space Telescope. (For comparison, the energy of visible light is between 2 and 3 electron volts.) The image contains 144 months of data from Fermi's Large Area Telescope; for better angular resolution, the map shows only gamma rays detected at the front of the instrument's tracker. Lighter colors indicate brighter gamma-ray sources. The images show the entire sky in galactic coordinates, in which the center is the center of our galaxy. The bright midplane of our galaxy runs across the images.
