Beskrivning:

These images show a region of the sky centered on the pulsar Geminga. Left: The total number of gamma rays detected by Fermi’s Large Area Telescope at energies from 8 to 1,000 billion electron volts (GeV) — billions of times the energy of visible light — over the past decade. Brighter colors correspond to greater numbers of gamma rays. Right: By removing all bright sources, astronomers discovered the pulsar’s faint, extended gamma-ray halo.
