Gravitational waves stretch and squeeze the fabric of space and time itself. When space/time is squeezed, pulsar pulses ...

New images show a collision of two enormous black holes, and it's the most distant black hole merger ever detected. The collision happened just 740 million years after the big bang event that ...

The collision itself happened eons ago — the two black holes are located about 9 billion light years from Earth. Scientists won't be able to document it for 10,000 years.

In the first collision, which was detected on 5 January 2020, a black hole six-and-a-half times the mass of our Sun crashed into a neutron star that was 1.5 times more massive than our parent star.

Two large black holes crashed together and formed a massive new one — the largest of its kind ever detected, so large that physicists weren't sure it could exist at all.

But black holes aren't too limited by size or number. On average, a standard black hole is about three to ten times the size of our sun. As massive as "regular" black holes can get, supermassive ...

A new model suggests how gravitational waves created by the collision between black holes spread and interact within the fabric of space-time.

The second detection, on Aug. 14, 2019, remains puzzling. The larger object in the collision was definitely a black hole. The smaller one had a mass of 2.6 times that of the sun.

That marked it as a possible black hole collision, he said. Bolstering that hypothesis was the fact that the flare did not become visible until 34 days after the gravitational waves were detected.

When the first black-hole collision was detected in 2015, it was a watershed moment in the history of astronomy. Using gravitational waves, astronomers were observing the universe in an entirely ...

Black hole collisions are so mighty they distort the very fabric of space-time, sending out gravitational waves across the cosmos. The waves wash over the Earth, and fine-tuned detectors allow us ...

The two black holes are on a collision course, but astronomers still aren’t sure whether they will – or can – merge. A.D. Goulding et al./Astrophysical Journal Letters 2019.
