Hubble catches gamma-ray burst with highest energy yet-recorded
Nov. 21 (UPI) -- With the help of the Hubble Space Telescope, scientists have characterized the gamma-ray burst GRB 190114C, which featured the highest energy ever recorded. 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 new...
