Cosmic Rays and Supernova Dust

NASA APOD

COSMIC MESSAGE

Cosmic rays, high-energy particles traveling near light speed, constantly bombard Earth. Discovered in 1912, their source was a long-standing mystery. A theory suggests these particles are atomic nuclei blasted from dust grains formed in supernovae. This illustration shows a supernova explosion and its expanding cloud of ejecta.
