WASHINGTON: Exploding supernova could be the “missing link” in understanding gamma-ray bursts (GRBs), one of the most powerful explosive events in the universe, according to new research. This finding could reveal secrets of the deaths of massive stars.
Supernova 2012ap was seen from Earth in 2012 as it exploded during the course of its death. Astronomers studying the remnants using the Very Large Array (VLA) of radio telescopes found that, although this event exhibited many of the characteristics of a supernova that would have produced a gamma-ray burst, no such release was detected. This marks the first time that such an event has been detected in the “middle ground” between GRB-producing occurrences and regular supernova.
These strange supernova release vast amounts of energy, but they are still not powerful enough to result in the production of gamma rays, the most energetic of all forms of electromagnetic radiation.
