If GRBs do occur this far into our universe, then radio emission was predicted to peak about a week after the optical emission . Now, late reports do indicate that radio emission has been detected and does peak a week later than the optical. This adds credibility to the claim that these bursts of gamma- radiation indeed occur far from our familiar home Galaxy . Shown above are two photos highlighting the changing optical emission from GRB970508 when it was increasing in brightness. Now light from this enigmatic explosion is fading.
