“Blinding Whole Galaxies, Destroying Millions of Worlds” –Rare Short Gamma Ray Burst Detected

 Short Gamma Ray Burst


A short gamma ray burst left the most-distant optical afterglow ever detected –incredibly faint and fast signals sometimes lasting mere hours–some 10 billion light years away, 3.8 billion years after the Big Bang. Astronomers suspect that up to one-third of all short gamma ray bursts come from merging neutron stars in globular clusters of old stars blinding whole galaxies with light and destroying millions of worlds. Known as SGRB181123B, it is the second most-distant well-established SGRB ever detected and the most distant event with an optical afterglow.
