NASA’s Fermi proves supernova remnants produce cosmic rays

A new study using observations from NASA’s Fermi Gamma-ray Space Telescope reveals the first clear-cut evidence the expanding debris of exploded stars produces some of the fastest-moving matter in the universe. This discovery is a major step toward understanding the origin of cosmic rays, one of Fermi’s primary mission goals.
