As NASA reports, two astronomers working with raw Webb data the space agency periodically makes available to researchers, ...

The largest black hole collision ever recorded has scientists' jaws on the floor — and scratching their heads.

Astrophysicists have analyzed two merging black holes; the team's best models suggest that at least one, if not both, of the black holes shouldn't exist.

"It was something I’ve never seen before and I’ve looked at tens of thousands of images of galaxies over my career," he said.

A gravitational wave has revealed the biggest black-hole merger ever recorded—so massive and extreme, it defies current astrophysical models. The clash formed a 225-solar-mass monster, possibly made ...

The merger wasn’t just the biggest ever, but also an event so rare that it challenges existing models for black hole genesis.

The LIGO Hanford Observatory near the Tri-Cities and its twin in Louisiana detected ripples of time and space passing through Earth from the most massive collision of black holes ever observed, a ...

The Trump administration has proposed closing either the LIGO Hanford observatory in WA or its twin in Louisiana.

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

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

Scientists have detected the merger of the most massive black holes ever observed with gravitational waves, using the US ...

For years, scientists have theorized that some black holes could actually be wormholes, and a new study shows that this space-time mimicry could in fact be possible.
