WHERE DO COSMIC RAYS COME FROM?


In case you were wondering…

“Cosmic rays are particles that streak through the universe at near-light speed, colliding with giant balls of gas. But their origins are shrouded in mystery. Now physicists have uncovered an important clue about where these superfast particles come from. Physicists used the Fermi telescope to examine how cosmic rays behave when they slam into giant balls of gas that are remnants from supernovas. Cosmic rays are mostly protons, and when they smash into these remnants, they are bounced around by magnetic fields and produce gamma rays.” (Click here for video and more.)
