Cosmic rays, which can cause disruptions of cell phones and satellite transmissions and are an important source of energy and particles in the galaxy, appear to formed by exploding stars and stellar "winds," researchers say, resolving, perhaps, one of the longtime mysteries of astrophysics. Using a state of the art telescope in southern Arizona, they have made observations as to how subatomic particles, mostly protons, can be hurled at top speeds by supernovae and stellar winds; they've focused their attention on starburst galaxy M82 with the super-sensitive Very Energetic Radiation Imaging Telescope Array System or VERITAS (truth) instrument.
Supernovae, stellar winds seem to hurl particles to top speeds to create cosmic rays
