NASA’s Fermi Gamma-ray Space Telescope show where supernova remnants emit radiation a billion times more energetic than visible light. The images bring astronomers a step closer to understanding the source of some of the universe’s most energetic particles – cosmic rays.

This composite shows the Cassiopeia A supernova remnant across the spectrum: Gamma rays (magenta) from NASA’s Fermi Gamma-ray Space Telescope; X-rays (blue, green) from NASA’s Chandra X-ray Observatory; visible light (yellow) from the Hubble Space Telescope; infrared (red) from NASA’s Spitzer Space Telescope; and radio (orange) from the Very Large Array near Socorro, N.M.
