A nearby galaxy's unusually bright radio signal reveals a black hole feeding more intensely, launching a particle jet like those seen in the early Universe.
A deep spectrum of a mysterious "little red dot" reveals a supermassive black hole cocooned in gas so dense it's opaque — but glowing in the infrared. The post "Little Red Dot" Is...
The black hole at the centre of a nearby galaxy is growing exceptionally fast, and is producing a burst of radio emission that has never been observed before. With characteristics...
The black hole accounts for over two-thirds the mass of the object it inhabits.

A new paper tries to show how 'gravastars' might mimic black holes without breaking relativity.
Which comes first, the galaxy or the black hole? We don't know, but scientists have long thought it could be the galaxy: Large stars within an existing galaxy consume their fuel an...
Black holes are already strange enough, regions of space where gravity is so extreme that not even light can escape. But physicists have long known there's another layer of weirdne...
If you happen to have an uncharged black hole handy, you may be able to power your house with it. Just set it spinning.Continue ReadingCategory: Physics,
Maps of the region around Sagittarius A*, the Milky Way's supermassive black hole, may reveal what happened to its missing wind.
Black holes are often misunderstood to be just that: dark and mysterious voids that are somehow akin to Alice in Wonderland’s mind-bending rabbit hole. But rather than a tunnel of...
Stellar mass black holes may not be black holes at all. Instead, they could be a type of extremely compact star called a gravastar, which mimics a black hole. This is according to...

A new mathematical breakthrough sheds light on how tiny black holes could emerge from critical states of spacetime. Black holes are often portrayed as cosmic giants, swallowing sta...
The core of the brightest galaxy in the cluster Abell 402 contains a curious void. New observations suggest that an ultra-massive black hole could have excavated this feature. The...
“There it is. There is the thing that everybody’s been looking for for 50 years.”
In a groundbreaking experiment, scientists have successfully replicated the extreme conditions found around black holes in a controlled laboratory environment. This remarkable feat...
A black hole shredded a massive star in a record-breaking explosion, but what astronomers discovered afterward may be even more remarkable. Black holes are among the most destructi...
You might think that black holes suck in light without letting it escape, but they actually concentrate light in the photon sphere which surrounds their horizon. In a recent paper,...
When a star strays too close to a supermassive black hole, it is torn apart in a brief, brilliant flare, and astronomers long assumed that was the end of the story. It isn't. Using...
Blackholes have fascinated scientists for a long time. There are many theories about what happens beyond them but there is always more work being done to discover their mysteries....
A feeding black hole at the heart of a nearby galaxy is behaving similarly to cosmic titans that existed just after the Big Bang.
