An article published in the journal “Nature” reports the observation of a gamma-ray burst (GRB) cataloged as GRB 171205A associated with a supernova cataloged as SN 2017iuk that was tens of times brighter than that type of event generally is, so as to fall into the category of hypernovae. A team of astronomers led by Luca Izzo of the Instituto de Astrofísica de Andalucía (IAA-CSIC) detected for the first time interaction between the jet that caused the GRB and the outer layers of the exploded star. This allowed to better understand the mechanisms that combine hypernovae and gamma-ray bursts, connected to a “hot cocoon”.
