New detections of gravitational waves brings the number to 11 – so far

More ripples in space-time have been detected from merging pairs of black holes, one of which was the most massive and distant gravitational-wave source ever observed.

At last, we’ve found gravitational waves from a collapsing pair of neutron stars

Astronomers have finally confirmed the source of the latest detected gravitational waves was the collission of a pair of neutron stars, what they'd been searching for all along.
