Chandra HETG Spectrum Shown here is the X-ray afterglow spectrum of GRB991216 obtained with Chandra's High Energy Grating Spectrometer (HETG).

Summary

Description	English: Chandra HETG Spectrum Shown here is the X-ray afterglow spectrum of GRB991216 obtained with Chandra's High Energy Grating Spectrometer (HETG). The HETG is one of two instruments aboard Chandra (the other being the Low Energy Grating Spectrometer) dedicated to high-resolution spectroscopy and can be used in conjunction with the ACIS or High Resolution Camera.

Image title	An international team of researchers used the Chandra X-ray Observatory to detect never-before-seen properties in the X-ray afterglow of a gamma-ray burst (GRB). GRBs are mysterious blasts of high-energy radiation, believed to be the most powerful explosions in the universe. Chandra's latest discovery of iron emission lines from the ejected material surrounding GRB991216 strengthens the case for a "hypernova" model for GRBs. In this theory, GRBs are caused by massive stars that collapse under their own weight, releasing gigantic amounts of energy.
