Summary

Astronomers may have detected the glimmer of a supernova explosion in the fading afterglow of a titanic gamma ray burst (GRB). The new results support the popular idea that GRBs--the most energetic explosions in the universe--are the birth cries of black holes, the collapsed remnants of dying stars. A second team studying supernova debris near another GRB has strengthened the black hole connection, but its observations challenge the conventional wisdom on the sequence of events.
