High-energy gamma rays detected from the Crab Nebula

LHAASO also detected a photon with an energy of 1.1 PeV (1 PeV is equal to one quadrillion electron volts or 1.1 million

billion electron volts).The find points to an extremely powerful electron accelerator located in the central region of the Crab Nebula. Its size is comparable to one tenth of the solar system.

Such an accelerator excites electrons to a levelwhich is 20,000 times the maximum index of CERN's Large Electron-Positron Collider (LEP). The parameters of the detected photon approached the absolute theoretical limit set by classical electrodynamics and ideal magnetohydrodynamics.

The photon supposedly originated from a high-energy electron that collided with it and propelled it to incredible energetic levels.

New evidence supports the hypothesis thatThe Crab Nebula is a supernova remnant, in the formation of which a neutron star took part. Scientists note that the discovery of new super-powerful rays will help science understand the mechanisms that are responsible for accelerating particles to colossal energies.

The Crab Nebula is 6500 light-years from Earth. It appeared as a result of a bright supernova explosion in 1054 AD. This is the first supernova remnant identified by modern astronomy with clear historical records. The nebula contains a powerful pulsar with a rotation period of 30 milliseconds. The rapidly rotating magnetosphere of the pulsar causes a powerful wind, consisting of electron-positron pairs moving at almost the speed of light. Electrons / positrons in a pulsar wind are accelerated to higher energies when the wind collides with the environment. The nebula is created by the radiation of accelerated electrons / positrons.
