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

If you viewed the sky with gamma-ray eyes, what would you see? To mark the discovery of thousands of gamma-ray sources, the Fermi team came up with unofficial constellations visible only in the highest-energy light. Explore them all: https://go.nasa.gov/4cYLVNp #FermiFriday | NASA Universe
