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
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.
