Last June, the consortium reported a second black hole merger, but the black holes involved weighed just 8 and 14 solar masses.
Not exact matches
Physicists concluded that the first detected gravitational waves, in September 2015, were produced during the final fraction of a second of the merger of two black holes to produce a single, more massive spinning black hole.
The merger generates powerful ripples in space called gravitational waves that kick the newly merged black hole away at speeds of hundreds or even thousands of kilometres per second.
A new study published in Nature presents one of the most complete models of matter in the universe and predicts hundreds of massive black hole mergers each year observable with the second generation of gravitational wave detectors.

This event, detected by the two NSF - supported LIGO detectors at 02:01:16 UTC on June 8, 2017 (or 10:01:16 pm on June 7 in US Eastern Daylight time), was actually the second binary black hole merger observed during LIGO's second observation run since being upgraded in a program called Advanced LIGO.
The first direct detection of gravitational waves occurred in mid-September 2015 (but announced February 11, 2016) with twin LIGO detectors in Hanford, WA and Livingston, LA (both USA) when ripples of spacetime from the last fraction of a second of the merger of two black holes with masses 29 and 36 solar masses combined to form a 62 - solar mass black hole with 3 solar masses of energy radiated away as gravitational waves in that last fraction of a second.
In 2005, astronomers announced that GRB 050709 and GRB 050509B may be have created by collisions involving two neutron stars (more from Chandra X-Ray Observatory) and ESO), but that the presence of a second flare by GRB 050724 was more likely to have been produced by a neutron star's merger with a black hole (ESO).
