You’ve probably heard of a supernova, when a star reaches the end of its life and explodes in a huge burst of energy. But these aren’t the only dramatic explosions out in space — there are also ...

Cataclysmic events happen in the universe all the time. Black hole mergers, supernovae, gamma-ray bursts, and a whole host of others. Most of them happen in distant galaxies, so they pose no threat to ...

A year ago, astronomers discovered a powerful gamma-ray burst (GRB) lasting nearly two minutes, dubbed GRB 211211A. Now, that unusual event is upending the long-standing assumption that longer GRBs ...
