How was the early universe after its birth? It didn’t have stars and galaxies. Instead, it was a simmering soup of particles such as quarks and gluons, with a few microscopic black holes popping up ...
There are black holes that are too big to be born from the death of a star but aren’t quite supermassive either. There’s ...
Scientists have developed a new technique that could turn black hole collisions into cosmic detectors for dark matter, ...
Scientists flew the XL-Calibur telescope on a high-altitude balloon to measure polarized X-rays from Cygnus X-1. These measurements reveal details about the chaotic, superheated material swirling ...
The early universe is absolutely so far outside our understanding of how the world works it's hard to describe in words. Back then, the cosmos wasn't filled with stars and galaxies but with a boiling ...
In 2023, a subatomic particle called a neutrino crashed into Earth with such a high amount of energy that it should have been impossible. In fact, there are no known sources anywhere in the universe ...
The knowledge that the galaxies in this Universe have black holes at their centers came to us gradually, like all things that have to do with space, starting in the 1970s. In the time that has passed ...

What if we were wrong about black holes?
Black holes are dense and scary. They suck up everything in their way. Their gravity is so strong it bends light and warps time. But what if I told you we might have been wrong about these cosmic ...
An artist's concept of a tidal disruption event (TDE), which happens when a star passes close to a supermassive black hole. The gravity of the black hole pulls material from the star and launches a ...
The early universe appears to be littered with enormous star-like balls of gas powered by a black hole at their core, a finding that has taken astronomers by surprise and might solve one of the ...
Imagine you’re standing in front of a closed door. Behind it is a teenager’s bedroom, and your task is to rate how messy it is on a scale of 1 to 10. But here’s the twist: you can’t open the door – ...
