Blasts of gamma rays from the distant universe may provide a new way to measure cosmic distances. These gamma ray bursts (GRBs) could help us understand the structure and expansion of the universe.

GRBs are the brightest events in the universe. They occur when huge stars die in supernova explosions or when massive objects such as neutron stars smash together, producing powerful flashes of radiation.
