Creation of Black Hole Detected Today

Fascinating news from the cosmos:

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.

Don’t forget that Gamma-Ray Bursts are the biggest known explosions in the universe, and are one of this things that could wipe out life on earth, if we were close enough.
