An illustration of NASA's Fermi spacecraft. The colors depicted in this illustration are for artistic purposes only.

Fermi observes gamma rays, the most energetic type of light, from extreme cosmic phenomena including gamma-ray bursts, active galaxies, supernova remnants, pulsars, and more. The mission has improved our understanding of dark matter and discovered the Fermi bubbles, two previously unknown massive structures extending above and below the plane of our galaxy, the Milky Way.

Launched: June 11, 2008
