Scientists marveled at the power of the gamma-ray jet, which likely marked the birth of a black hole. Astronomers have since been trying to work out what could have made the gamma-ray burst so bright, and may finally have an answer. Researchers have discovered that the gamma-ray explosion ejected a jet with an unusual structure which dragged a large amount of stellar material along with it. The analysis demonstrates that the most extreme explosions do not obey the standard physics assumed for normal gamma-ray bursts, he said. Still, according to O'Connor, this finding "a massive step forward in our understanding of gamma-ray bursts," the "equivalent Rosetta stone of long GRBs."
