NASA Animation of Gamma-ray Burst 130427A

 

 

The leading theory explaining long gamma ray bursts such as GRB 130427A posits that they are created during the most energetic explosions in the cosmos, which occur when a very massive star collapses on itself. When the core of a massive star collapses, it can eject a jet of gas into space at nearly the speed of light. Collisions between the fast-moving gas and its surroundings, as well as within the jet itself, create gamma rays. This NASA-Goddard animation depicts the cosmic event that culminated in GRB 130427A.
