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.
The black hole accounts for over two-thirds the mass of the object it inhabits.
The event horizon of a black hole should be impossible to study. It’s the point of no return, the boundary where gravity grows so strong that not even light can escape, so by defin...
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...
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...
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...
Maps of the region around Sagittarius A*, the Milky Way's supermassive black hole, may reveal what happened to its missing wind.
The area surrounding our galaxy’s central supermassive black hole contains three strangely different populations of stars – but one hidden black hole could explain all of them
“There it is. There is the thing that everybody’s been looking for for 50 years.”
A feeding black hole at the heart of a nearby galaxy is behaving similarly to cosmic titans that existed just after the Big Bang.
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...
Scientists have long suspected that this star cluster was a hotspot for a certain kind of black hole. But for decades, they had been unable to spot any
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...

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...
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...
Astronomers have detected one of the most powerful ultra-fast outflows ever seen from a distant supermassive black hole. Using XMM-Newton and NuSTAR, a team studied a hyper-luminou...
An international team led by Stefanie Komossa from the Max Planck Institute for Radio Astronomy (MPIfR) in Bonn has studied a galaxy that has been shining exceptionally brightly in...
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...
Inside some very special black holes, there may be a boundary called a Cauchy horizon. Columnist Leah Crane explores the place beyond which physics breaks and anything is possible
Evidence suggests that the 50m-solar-mass black hole predates its host galaxy. Read more: NASA’s Webb telescope reveals black hole formed before galaxy
A new paper tries to show how 'gravastars' might mimic black holes without breaking relativity.
Astronomers offer more support that the James Webb Space Telescope's "little red dots" discoveries may contain massive black holes.
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,
