by Australian National University:

Scientists, including from The Australian National University (ANU), say they have detected a black hole swallowing a neutron star for the first time.

Neutron stars and black holes are the super-dense remains of dead stars.

On Wednesday 14 August 2019, gravitational-wave discovery machines in the United States and Italy detected ripples in space and time from a cataclysmic event that happened about 8,550 million trillion kilometres away from Earth.

Professor Susan Scott, from the ANU Research School of Physics, said the achievement completed the team's trifecta of observations on their original wish list, which included the merger of two black holes and the collision of two neutron stars.
