NASA | Fermi at Five Years

The Fermi Gamma Ray Space Telescope, launched in 2008, has made significant contributions to our understanding of the universe. It has observed gamma rays from various cosmic events, confirmed Einstein's theory of space-time, and provided insights into dark matter. Fermi has also detected supernova remnants, pulsars, and solar flares, revealing new information about cosmic rays and antimatter. The telescope's continuous operation has been crucial, even avoiding a potential collision with a defunct satellite, ensuring ongoing scientific discoveries.
