The Latest Breaking News from Black Hole

How big can 'ultramassive' black holes get? Scientists may have the answer

Scientists may have discovered a limit to how massive black holes can grow. If they're right, we may have already discovered the largest possible ultramassive black hole!

Sweeping gravitational wave map of the universe could reveal hidden black holes

A map of the universe in gravitational waves could reveal "hidden" black holes, supermassive black hole collisions, and the large-scale structure of the cosmos.

Some black holes at the centers of galaxies have a buddy − but detecting these binary pairs isn’t easy

Every galaxy has a supermassive black hole at its center, much like every egg has a yolk. But sometimes, hens lay eggs with two yolks. In a similar way, astrophysicists like us who study supermassive black holes expect to find binary systems – two supermassive black holes orbiting each other…

Are planet-killing black holes hiding inside your cat?

New research suggests that tiny primordial black holes could be hollowing out planets and passing through everyday objects, maybe even you and your cat!

Space

To map the vibration of the universe, astronomers built a detector the size of the galaxy

Using the largest gravitational wave detector ever made, we have confirmed earlier reports that the fabric of the universe is constantly vibrating. This background rumble is likely caused by collisions between the enormous black holes that reside in the hearts of galaxies.

Naked singularities: how quantum black holes explain why we don’t see the end of space and time

Albert Einstein’s theory of gravity, general relativity, is famously incomplete. As proven by physics Nobel laureate Roger Penrose, when matter collapses under its own gravitational pull, the result is a “singularity” – a point of infinite density or curvature.

'Hidden black hole' devouring curious star exposed by new X-ray space telescope

In a "rite of passage," the JAXA/NASA X-ray telescope XRISM has mapped in detail Cygnus X-3, a curious binary system with a potential black hole feasting stellar winds blowing from a massive star.

The Sombrero Galaxy's star-forming days are nearly over — and the James Webb Space Telescope may know why

A brand-new James Webb Space Telescope image captures the steady, slow lifestyle of the distinctive Sombrero Galaxy.

Black hole quiz: How supermassive is your knowledge of the universe?

Black holes have captivated scientists for more than a century. How well do you know these supermassive wonders of the universe?

Unusual black hole light bursts puzzle astronomers: 'We are finding a lot of weird stuff'

Astronomers have stumbled upon a pair of massive black holes in a distant galaxy that are triggering unusual bursts of light that may be caused by the black hole duo disrupting a massive gas cloud — a phenomenon researchers say is the first of its kind to be detected.

Space

'Impossible' black holes discovered by the James Webb telescope may finally have an explanation

Peculiar James Webb Space Telescope observations seem to show gargantuan black holes in the earliest moments of the universe. New research may explain how they formed, thanks to primordial "seeds".

Supermassive black holes bent the laws of physics to grow to monstrous sizes

Scientists may have cracked one of the biggest mysteries in space science, determining that supermassive black holes bent the laws of physics to grow to their huge sizes.

Dark matter might make space-time ring like a bell around black holes — and we might be able to 'hear' it

To explain why dark matter particles haven't come up in any direct detection experiments, physicists have wondered if it may be a kind of particle known as an axion.

Egg-shaped galaxies may be aligned to the black holes at their hearts, astronomers find

Black holes don’t have many identifying features. They come in one colour (black) and one shape (spherical).

Supermassive black holes prefer to eat from wobbly plates

Researchers have discovered the first evidence that the brightest accretion disks around supermassive black holes "wobble" as their monstrous occupants drag them around.

'Fastest-feeding' black hole of the early universe found! But does it break the laws of physics?

The hungriest known black hole in the early universe has been found, thanks to teamwork between NASA's James Webb Space Telescope and Chandra X-ray Observatory.

'Hawking radiation' may be erasing black holes. Watching it happen could reveal new physics.

Primordial black holes may be exploding throughout the universe. If we can catch them in the act, it could pave the way to new physics, a study suggests.
