The biggest black hole merger yet observed could confirm a rare class of black holes long thought to be missing from the universe.

The only place that's likely to happen is at the very center of our galaxy. And, for a while, there was an excess of ...

Hidden in the ‘Infinity Galaxy,’ a black hole floats in space where none should exist, upending old ideas about black hole birth.

Everything about the Infinity Galaxy, recently discovered by the JWST, is strange. One odd feature could be the 1st evidence ...

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

L ast month, work began on the world’s first space-based gravitational wave detector. The European Space Agency and partner aerospace companies are developing orbiting, detector spacecraft to observe ...

"One day soon we may be able to see these 'missing' galaxies, which would be hugely exciting and could tell us more about how the universe came to be as we see it today." ...

“Third, as an unexpected bonus, it turns out that both galaxy nuclei also have an active supermassive black hole. So, this ...

Astronomers have detected the signal of a colossal black hole in deep space that likely formed when two already-large black ...

Astronomers have detected the most massive black hole merger ever observed, challenging stellar evolution and black hole formation theories.

A collision observed between two black holes, each more massive than a hundred suns, is the largest merger of its kind ever ...

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.
