> A faint visible-light flash moments after a high-energy gamma-ray burst likely heralds the merger of two dense neutron stars to create a relatively low-mass black hole, said Neil Gehrels of NASA’s Goddard Space Flight Center. It is the first time an optical counterpart to a very short-duration gamma-ray burst has ever been detected.
> 
> Gamma rays are the most energetic form of radiation on the electromagnetic spectrum, which also includes X-rays, light and radio waves.
> 
> The merger occurred 2.2 billion light-years away, so it actually took place 2.2 billion years ago and the light just reached Earth this morning.
> 
> **Quick global effort**
> 
> Gehrels said the burst occurred just after midnight East Coast time. It was detected by NASA’s orbiting Swift telescope. Swift automatically repositioned itself within 50 seconds to image the same patch of sky in X-rays. It just barely caught an X-ray afterglow, Gehrels said in a telephone interview.
> 
> The X-ray counterpart was barely detectable and only observed for a few minutes.
