A U.S. gravitational wave detector spotted a collision between fast-spinning “forbidden” black holes that challenge physics ...

“It’s the most massive [merger] so far,” says Mark Hannam, a physicist at Cardiff University, UK, and part of the LVK ...

Scientists predict one of the major surveys by NASA's upcoming Nancy Grace Roman Space Telescope may reveal around 100,000 celestial blasts, ranging from exploding stars to feeding black holes. Roman ...

This artist's concept visualizes a kilonova – an explosion that happens when two neutron stars or a neutron star and a black hole collide and merge. When these collisions happen, a fraction of the ...

The new black hole has more than 200 times the mass of our sun – and is challenging theories of how objects form in space ...

Discoveries keep pouring out of the James Webb Space Telescope (JWST). Researchers observed an unusual cluster, which they ...

Yale astronomer Pieter van Dokkum and a team of researchers have discovered an object in space they call the "Infinity" ...

Gravitational waves spotted by LIGO reveal two black holes, 140 and 100 times the mass of the sun, merged to become a 225 solar mass behemoth.

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