There are two main types of black hole; stellar mass and supermassive black holes, and they differ in size, formation, and impact on their host galaxy. Stellar mass black holes, a few to dozens of ...

For the first time, astronomers have confirmed the existence of a lone black hole — one with no star orbiting it. It’s “the only one so far,” says Kailash Sahu, an astronomer at the Space ...

After decades of inactivity, the black hole at the galaxy's heart burst with light. Now, the cosmic monster appears to be doing something that is forcing astronomers to re-evaluate their ...

A groundbreaking study,published in March 2025 on the preprint server arXiv, reveals that ultralight dark matter might have ...

Simulations of highly magnetized stars that explode and collapse into black holes show that they transfer their magnetic fields to the disk of swirling matter that forms around the new black hole.

We've all woken up in a terrible mood from time to time, but a newly observed monster black hole is really having a bad day. The previously inactive supermassive black hole at the heart of the ...

Astronomers think there could be as many as 100 million black holes in our galaxy ... why it is a solitary wanderer might be due to its formation. The supernova explosion that created it must ...

Get Instant Summarized Text (Gist) Supermassive black holes can strip subgiant stars of their outer layers, leaving behind dense helium cores. These cores, in close orbit around the black hole ...

Scientists have discovered key conditions needed for a stellar black hole to create plasma jets. Their findings show that when superheated gas material experiences a rapid shrinkage towards the black ...

Black holes are bounded by outer barriers called event horizons that prevent us from ever viewing their interiors or their hearts, singularities at which all known laws of physics collapse.

Black holes, the densest objects in the universe, eat up anything that comes too close, even light. Is there anything left inside these behemoths that could reveal what they devoured in the first ...
