The most extreme black hole collision ever recorded looked, at first, like it should not have happened at all. Two objects each weighing roughly as much as one hundred Suns crashed together in a ...

An illustration of two stellar-mass black holes merging in the accretion disk of an active galactic nucleus. (Shu-Rui Zhang) ...

Scientists may have solved a cosmic mystery that has been troubling them since the James Webb Space Telescope (JWST) began observations back in 2022. When astronomers started looking back into the ...

Here’s what you’ll learn when you read this story: Black holes usually form from stars that burn out and collapse in on themselves, but that cannot explain the red spark of light that could be a ...

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) ...

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 ...

If a new proposal by physicists bears out, the recent detection of a record-setting neutrino could be the first evidence of elusive Hawking radiation. (Nanowerk News) The last gasp of a primordial ...

Scientists found exotic prime numbers may play a role in black hole physics, revealing a surprising connection between number theory and the extreme environments of the universe.

Black holes are eaters of all things, even radiation. But what if their rapacious appetites had an unexpected side effect? A new study published in Physical Review Letters suggests that black holes ...

"If our hypothesized dark charge is true, then we believe there could be a significant population of primordial black holes, which would be consistent with other astrophysical observations, and ...

A bright star in a nearby galaxy has essentially vanished. Astronomers believe that it died and collapsed in on itself, transforming into the eerie cosmic phenomenon known as a black hole. "It used to ...

The last gasp of a primordial black hole may be the source of the highest-energy “ghost particle” detected to date, a new MIT study proposes. In a paper appearing today in Physical Review Letters, MIT ...
