SUMMARY: An international team of astronomers have found evidence that certain kinds of gamma-ray bursts, which are associated with Type 1C supernovae (aka hypernovae), could be caused when carbon/oxygen stars collapse into black holes. Type 1C supernovae occur when massive stars shed their outer layers of hydrogen and helium, or lose them to binary companions. As it collapses, material blasts out the top and bottom in powerful jets. The team was able to confirm this model by using Keck and the Subaru Telescope to analyze a recent hypernova that matched their predictions perfectly.
