Via a press release from one of the Universities in the LIGO team:

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.

...

"The ANU SkyMapper Telescope responded to the detection alert and scanned the entire likely region of space where the event occurred, but we've not found any visual confirmation."

Scientists are still analysing the data to confirm the exact size of the two objects, but initial findings indicate the very strong likelihood of a black hole enveloping a neutron star. The final results are expected to be published in scientific journals.

Hallo! Hier ist eine

Hallo!

Hier ist eine deutschsprachige Beschreibung des Ereignisses, soweit die Daten bisher alanysiert sind :

Wir werden abwarten müssen, was die genaueren Analysen ergeben.

Kind regards and happy crunching

Astronomers probably just saw

Ripples in the fabric of spacetime reveal what may be a first-of-its-kind cosmic collision.
