Supernova Reserve Fuel Tank Clue to Big Parents
Canberra, Australia (SPX) May 20, 2016
Some supernovae have a reserve tank of radioactive fuel that cuts in and powers their explosions for three times longer than astronomers had previously thought. A team of astronomers jointly led by Dr. Ivo Seitenzahl from The Australian National University (ANU) detected the faint afterglow of a supernova, and found it was powered by radioactive cobalt-57. The discovery gives important new clues about the causes of Type Ia supernovae, which astronomers use to measure vast distances across the univ ... read more
