Series of radio images of FIRST J1419+3940 from 1993 to 2017 show its slow fade. Astronomers comparing data from an ongoing major survey of the sky using the National Science Foundations Karl G. Jansky Very Large Array (VLA) to data from earlier surveys likely have made the first discovery of the afterglow of a powerful gamma ray burst that produced no gamma rays detectable at Earth. The unprecedented discovery of this orphan gamma ray burst (GRB) offers key clues to understanding the aftermath of these highly energetic events.
