Using JWST and ALMA data, astronomers have spotted a superlong and narrow 'galactic contrail,' possibly produced by a black ...

You've heard of a supermassive black hole. Now, what about an "ultramassive" black hole? That descriptor is the only word researchers could use befitting a black hole recently spotted lurking far from ...

For the first time, astronomers have directly measured a solar-system-size corona around a distant supermassive black hole, thanks to a rare cosmic alignment.

In this instance, two enormous black holes – 100 and 140 times the mass of Earth's sun – collided. The result? A black hole the size of a whopping 240 suns. Black holes this massive shouldn't be ...

Astronomers have spotted an apparent supermassive black hole snacking on a star 600 million light-years away, wandering through a galaxy with an even larger black hole at its core. The event, dubbed ...

Back in 1971, the late physicist Stephen Hawking made an intriguing prediction: The total surface area of a black hole cannot decrease, only increase or remain stable. So if two black holes combine, ...

Astronomers have discovered the oldest and most distant black hole — a behemoth that likely formed at the dawn of the universe, more than 13 billion years ago. The black hole lies at the center of a ...

A study in Nature finds that black holes in the early Universe go through short periods of ultra-fast growth, followed by long periods of dormancy. Scientists have spotted a massive black hole in the ...

Researchers believe the 'ultramassive' black hole is big enough to be the largest of its kind ever detected. Black holes are regions of space where the pull of gravity is so intense that even light ...

Sometime in their cosmic lives, two gigantic black holes crashed into one another to form something even more monstrous: A black hole equal to the size of 240 of Earth's sun. Now, thanks to an ...
