The Crab Nebula Just Sent Earth the Highest-Energy Photons Ever Recorded

Astronomers using the Tibet AS-gamma Experiment have discovered the highest-energy light ever measured from an astrophysical source. Photons streaming from the Crab Nebula were recently measured at energies well over 100 tera-electronvolts (TeV). That’s a trillion electron volts, or some 10 times the maximum energy that the Large Hadron Collider sees when it slams particles together.
