The merger of two neutron stars, observed in August, created two powerful jets streaming away into space at nearly the speed of light, in agreement with theoretical predictions and shedding new light on gamma ray bursts.

LIGO’s twin black holes might have been born inside a single star

24 February 2016 Astronomy Now

On 14 September 2015, the Laser Interferometer Gravitational-wave Observatory (LIGO) detected gravitational waves from the merger of two black holes 29 and 36 times the mass of the Sun. New research suggests that the two black holes might have resided inside a single, massive star whose death generated a gamma-ray burst detected by the Fermi Space Telescope.
