Gravitational-wave detectors have captured their biggest spectacle yet: two gargantuan, rapidly spinning black holes likely ...

Astronomers have been aware of cosmic vampires, dead stars that hungrily strip plasma from victim stars, for some time. New ...

New gravitational wave findings from the LIGO-Virgo-KAGRA Collaboration report the discovery of the largest black hole merger ...

Our Milky Way could have many more satellite galaxies than we've detected so far. They're just too faint to be seen.

The event is the most massive black hole merger ever recorded by gravitational wave detectors and has forced physicists to ...

This colossal collision, which occurred about 10 billion light-years from Earth, was detected in November 2023 by the Laser Interferometer Gravitational-Wave Observatory (LIGO) detectors located in ...

Scientists have detected the collision of two massive black holes merging beyond the Milky Way. The two black holes, each ...
