A source of extremely high-energy particles in the Milky Way identified

Cosmic rays are made primarily of protons with a few electrons sprinkled in, and they can reach energies even higher than what human-made accelerators can produce.

Considering human-made accelerators, such as the Large Hadron Collider on the border of Switzerland and France, can move protons to near the speed of light, it's no wonder that these super-energetic particles can influence cosmic events across the galaxy. ...
