Gamma-ray bursts in the sky

Clemson University says its astrophysicist, Dieter Hartmann, was part of an international team of astronomers that obtained observational evidence of rare heavy elements in the aftermath of a cataclysmic explosion triggered by the merger of two neutron stars.  It was a massive explosion, says Clemson, that unleased a gamma-ray burst.  The team used ground-based telescopes, including NASA’s James Webb Space Telescope, and pinpointed the source of the burst in the sky and tracked how its brightness changed.
