For decades researchers have thought that the cosmic rays that come to the Earth from the edges of the galaxy begin in stars that go supernova. Researchers can be sure that such cosmic rays are reaching us – and at such high velocities – because of experiments including the High-Altitude Water Cherenkov observatory near Puebla, Mexico, which uses big metal tanks of water that light up when they are struck by high-energy particles. Instead, the fast cosmic rays in fact seem to be comign from star clusters that serve as accelerators and throw the particles across the galaxy with such intense amounts of energy, according to new research.
