Supermassive black holes are among the most enigmatic objects in the universe. They typically weigh millions or even billions ...

Some things in cosmology may simply be unknowable. Why is there something rather than nothing? What lies outside the universe? What is inside a black hole? That last one has been niggling at ...

New research suggests that relic black holes from before the big bang may still shape galaxies today. These black holes could ...

Black holes are among the most extreme objects in the universe, and now scientists can model them more accurately than ever before. By combining Einstein’s gravity with realistic behavior of light and ...

The majority of the merging black holes are around 10 solar masses.

A new simulation could help solve one of astronomy’s longstanding mysteries—how supermassive black holes formed so rapidly—along with a new one: What are the James Webb Space Telescope’s (JWST) ...

Whenever someone talks about black holes, they almost always talk about the event horizon and the singularity. After all, that's what defines a black hole, right? Well, it depends on what you mean by ...

Last year, astronomers were fascinated by a runaway asteroid passing through our solar system from somewhere far beyond. It was moving at around 68 kilometres per second, just over double Earth's ...

Physicists may soon witness a cosmic fireworks show: the explosive death of a primordial black hole. Once thought to be unimaginably rare, new research suggests there’s up to a 90% chance of catching ...

"We can study a diverse population of supermassive black holes and their radio jets at different stages of their evolution." When you purchase through links on our site, we may earn an affiliate ...

We only have actual pictures of two black holes, taken using the Earth-sized Event Horizon Telescope. These images look like doughnuts seen face-on, with a central hole, but the discs aren’t really ...

A runaway black hole leaving a streak of new stars in its wake. James Webb Space Telescope / van Dokkum et al. Last year, astronomers were fascinated by a runaway asteroid passing through our Solar ...
