Space scientists may need to rethink how gamma-ray bursts are formed after new research shows new-born supramassive stars, not black holes, are sometimes responsible for these huge extragalactic bursts of energy.
Gamma-ray bursts (GRBs) have been detected by satellites orbiting Earth as luminous flashes of the most energetic gamma-ray radiation lasting milliseconds to hundreds of seconds. These catastrophic blasts occur in distant galaxies, billions of light years from Earth.
A sub-type of GRB known as a short-duration GRB starts life when two neutron stars collide...
