An international team of physicists discovered the largest-ever merger of 2 black holes through a phenomenon known as gravitational waves.

Two colossal black holes—among the most massive ever seen—collided in deep space, creating gravitational waves that rippled across the cosmos and shook the foundations of astrophysical theory.

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 ...

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

For the first time, astronomers have spotted a star that exploded not once, but twice. A new image of a roughly 300-year-old supernova provides visual evidence that some dying stars undergo a double ...

The massive black hole has been dubbed GW231123. Its unusual size and behavior is challenging scientists' understanding of ...

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

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

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

There’s a chance we could see a white dwarf star explosion this year. T Coronae Borealis, a binary star system and recurrent nova located roughly 3,000 light-years from Earth, is expected to erupt ...

Dark matter remains one of science's deepest mysteries. It makes up about 25% of our universe, yet scientists only observe ...
