The Mechanisms Driving Cosmic Ray Acceleration in Supernova Remnants
Quick fact
Supernova remnants accelerate cosmic rays to energies up to a few petaelectronvolts (PeV), making them some of the most powerful particle accelerators in the universe, surpassing the Large Hadron Collider's maximum energy by a factor of a million.
Why this is interesting
You've probably seen fireworks, but did you know that exploding stars act as nature's own particle accelerators, flinging particles across the galaxy?
