GRB 190114C was an extreme gamma-ray burst explosion from a galaxy 4.5 billion light years away (z=0.4245;[2] magnitude=15.60est[3]) near the Fornax constellation,[4][5][6] that was initially detected in January 2019.

[3][7] The afterglow light emitted soon after the burst was found to be tera-electron volt radiation from inverse Compton emission, identified for the first time.

"[9] Recent publications following the event indicate that inverse Compton scattering is the mechanism responsible for producing TeV photons.

[10][11][12][13] Researchers "have been trying to observe such very high energy emission from GRB's for a long time, so this detection is considered a milestone in high-energy astrophysics".

[4][14] The most recent studies propose, in summary, a model of binary system of hypernova (BdHN I) with two neutron stars, where one of them collapses in a black hole, surrounded by an accretion disk and from whose poles the GRB is launched.
