Astronomers May Have Finally Connected Supernovae and Gamma Ray Bursts

The link between gamma ray bursts (GRBs) and supernovae has been a confusing one. GRBs are highly energetic jets that blast from massive star explosions, but not all powerful supernovae produce them. Their sporadic nature has puzzled scientists for decades, but now, they might finally have some answers.

During a recent study of a distant GRB, researchers saw a “cocoon” of energy surrounding it. They believe that GRBs create these cocoons by transferring energy to them, and if they transfer too much, they become too weak to shine through the star and become visible. These findings, which could explain why powerful supernovae don’t always produce GBRs, were published on January 16 in the journal Nature.

The European Space Agency may create a new mission, called THESEUS, which will be tasked with increasing the accuracy of the information when GRBs are used to measure distances.
