Ancient quasars seen by the James Webb Space Telescope technically shouldn’t exist, but one rare type of dark matter could ...

The passing gravitational waves “stretch or contract the universe by around 20 meters [about 65 feet] or so,” says Matthew ...

"They are everywhere!" A terrifying finding made in a solar system void. The discovery of a record-mass stellar black hole in our galaxy.

Recent studies have shown that our entire solar system may serve as a gigantic PBH detector, with these little black holes leaving their faint but very possibly detectable ...

"This is the first solid evidence that helical magnetic fields can explain astrophysical jets at different scales." ...

By observing tiny ripples in spacetime called "gravitational waves" that propagate away from colliding black holes, ...

After decades of study, scientists sound genuinely optimistic about the possibility of detecting primordial black holes, which might explain dark matter.

In contrast, the supermassive black hole itself is on the order of 1 million solar masses ... The team plans to continue observing the system, with existing and future telescopes, to better ...

Researchers found for the first time evidence that even microquasars containing a low-mass star are efficient particle accelerators, which leads to a significant impact on the interpretation of the ...

Our home planet is bombarded with particles from outer space all the time. And while we are mostly familiar with the rocky meteorites originating from within our solar system that create fascinating ...

A black hole infamous for strange features has once again baffled astronomers, this time with rapid X-ray flashes. What could they be?

(via PBS Space Time) Dark matter has eluded us for many decades. Even our most advanced particle colliders and sophisticated underground detectors have come up short. But it may be that we can finally ...
