Could a black hole pass through our solar system at high speed? This possibility, once confined to science fiction, is becoming increasingly tangible thanks to recent observations. This theory ...

The catalog of gravitational waves "heard" by LIGO, KAGRA and Virgo has doubled with detections of spacetime ripples.

A new study published in Nature Astronomy indicates that the dense, star- and dark-matter–rich environments around supermassive black hole binaries pack on the order of a million solar masses into ...

Detecting supermassive black holes just before their merger would lead to significant advances in astrophysics. To achieve this, a new innovative approach combines the study of the gravitational ...

When the densest objects in the universe collide and merge, the violence sets off gravitational waves that reverberate across space and time over ...

The results reveal that our universe is reverberating with cosmic collisions. Some of the waves stem from pairs of black ...

When the densest objects in the universe collide and merge, the violence sets off ripples, in the form of gravitational waves ...

Collaboration has published its latest compilation of gravitational-wave detections, showing the universe is echoing all over with a kaleidoscope of cosmic collisions.

A subtle gravitational-wave “hum” from merging black holes may help settle the cosmic fight over how fast the universe is ...

Hypothetical dark matter stars known as ‘boson stars’ could leave telltale ripples across the cosmos, offering researchers a new way to probe the invisible forces shaping the universe. By Jonathan ...

Another describes a long straight contrail cutting across a galaxy called NGC3627. This one is likely caused by a black hole of about 2 million times the mass of the sun, travelling at 300km/s. Its ...
