Awesome Fermi Gamma-ray Space Telescope Sees No Gamma Rays from Nearby Supernova ! Even when it doesn’t detect gamma rays, NASA’s Fermi Gamma-ray Space Telescope helps astronomers learn more about the universe. A nearby supernova in 2023 offered astrophysicists an excellent opportunity to test ideas about how these types of explosions boost particles, called cosmic rays, to near light-speed. But surprisingly, NASA’s Fermi Gamma-ray Space Telescope detected none of the high-energy gamma-ray light
