TEHRAN, Nov 23_With the help of the Hubble Space Telescope, scientists have characterized the gamma-ray burst GRB 190114C, which featured the highest energy ever recorded.
TEHRAN, Young Journalists Club(YJC)_The record-setting gamma-ray burst was first spotted in January by several telescopes, including NASA's Swift and Fermi telescopes. Shortly after its discovery, several other powerful telescopes, including space-based observatories like Hubble, set out to image the powerful object in greater detail.
Earlier observations suggest material ejected during the gamma-ray burst explosion reached speeds of 99.999 percent the speed of light. As this material passed through gas surrounding the collapsing star, a shock wave was produced. The shock wave triggers the burst of gamma rays measured by observatories on Earth.
The newest Hubble images -- described this week in the journal Nature -- are helping scientists begin to figure out exactly how the collapsing cores of dying massive stars produce such high energy gamma rays.
