    "description": "This image shows the entire sky as seen by Fermi's Large Area Telescope. Lighter colors indicate brighter gamma-ray sources. The map is centered on the center of our galaxy. The most prominent feature is the bright, diffuse glow running along the middle of the map, which marks the central plane of our Milky Way galaxy. The gamma rays there are mostly produced when energetic particles accelerated in the shock waves of supernova remnants collide with gas atoms and even light between the stars. Many of the star-like features above and below the Milky Way plane are distant galaxies powered by supermassive black holes. Many of the bright sources along the plane are pulsars. The image was constructed from 15 years of observations using front-converting gamma rays with energies greater than 1 GeV.

The image contains 60 months of data from Fermi's Large Area Telescope; for better angular resolution, the map shows only gamma rays converted at the front of the instrument's tracker. Brighter colors indicate brighter gamma-ray sources. The map is shown in galactic coordinates, which places the midplane of our galaxy along the center. The five-year Fermi map is available in multiple resolutions below, along with additional plots containing reference information and identifying some of the brightest sources. || ",
