Crab Nebula blasts Earth with highest-energy photons ever recorded

astronomy.com
  • The Tibet AS-gamma Experiment has picked up the highest-energy light ever measured.
  • Signal measured at over 100 tera-electronvolts (TeV) is 10 times the maximum energy the Large Hadron Collider sees when smashing particles.
  • Sending the signal might be a pulsar, the core of a post-supernova star, deep inside the Crab Nebula.
  • In total, 24 events greater than 100 TeV were picked up, the most powerful reached 450 TeV.
  • The next challenge for astronomers will be finding signals stronger than 1,000 TeV.
