Cosmic Rays are high energy particles, with typical energies up to about 0.3 GeV (4.8 × 10-11 Joule), but the highest energy have been up to 3 × 1011 GeV. They include both photons (Photon Ray or Photonic Ray) and atomic nuclei (Fermion Ray or Fermionic Ray). They are theorized to be formed largely by supernovae.
A famous graph, the Swordy Plot demonstrates that Cosmic Rays occur basically in a Power Law Spectrum over a wide range.
