Strange Supernova is 'Missing Link' in Gamma-Ray Burst Connection - National Radio Astronomy Observatory

Astronomers using the National Science Foundation's Very Large Array (VLA) have found a long-sought 'missing link' between supernova explosions that generate gamma-ray bursts (GRBs) and those that don't. The scientists found that a stellar explosion seen in 2012 has many characteristics expected of one that generates a powerful burst of gamma rays, yet no such burst occurred.
