It was a Pac-Man thing.
A neutron star got eaten by a black hole, and let out a howl.

The dinner date in question occurred 900 million years ago, and the “scream” consisted of gravitational waves, which unlike sound can travel through the near-vacuum of space. Like rocking a boat, you might say.
While not observed before last year, it’s not surprising that black holes eat neutron stars. After all, they eat everything else.
