The Vela pulsar is a type of neutron star made up of photons with energies measured to be higher than one teraelectronvolt. The specimen is said to be located some 1,000 light-years from Earth, and spans about 12 miles in diameter.
Astronomers were recently left astounded when the Vela pulsar unleashed on Earth an energy burst of 20 trillion electron volts - the most high-energy gamma rays ever detected from a pulsar [...]

Powerful Energy From Mysterious 'Dead Star' Strikes Earth, Leaves Scientists Stunned
Earth was hit by a 20trl electron volts burst of energy from a dead star known as the Vela pulsar, thus challenging existing knowledge of pulsars, as it was the highest ever recorded emission.

Discovery of a radiation component from the Vela pulsar reaching 20 teraelectronvolts - Nature Astronomy
The H.E.S.S. gamma-ray observatory has observed gamma rays with energies of at least 20 TeV from a pulsar, an energy regime that is hard to reconcile with the existing theories of gamma-ray production for such objects.
