GRB 190114C

GRB 190114C
The Hubble Space Telescope caught the fading afterglow of GRB 190114C and its home galaxy on February 11 and March 12, 2019. The difference between these images reveals a faint, short-lived glow (center of the green circle) located about 800 light-years from the galaxy’s core. Blue colors beyond the core signal the presence of hot, young stars, indicating that this is a spiral galaxy somewhat similar to our own. The source of the burst is located about 4.5 billion light-years away in the direction of the constellation Fornax.

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.[8] According to the astronomers, "We observed a huge range of frequencies in the electromagnetic radiation afterglow of GRB 190114C. It is the most extensive to date for a gamma-ray burst."[8] Also, according to other astronomers, "light detected from the object had the highest energy ever observed for a GRB: 1 Tera electron volt (TeV) -- about one trillion times as much energy per photon as visible light";[4] another source stated, "the brightest light ever seen from Earth [to date].".[9]
