In one new theory, it is possible that dark matter exists in a mirror universe where there are only dark versions of forces ...

Violent black hole collisions may create black hole 'morsels' no larger than an asteroid — and these bizarre objects could pave the way to unlocking new physics, a study claims.

Astronomers have measured the weight of a huge black hole — 36 billion times the mass of our sun, or six times the size of our entire solar system — in an old and dead galaxy near Earth. This cosmic ...

Black holes are dark, menacing objects with gravity so intense that not even light can escape, so you don’t want to mess with them. A recent discovery of one of the strangest supernovas ever observed ...

Using AI, astronomers discover a new type of supernova, SN 2023zkd, the strongest evidence yet of a dying star being ...

The scenario closest to the observations, the researchers determined, involved a massive dying star and a compact object such ...

"We're now entering an era where we can automatically catch these rare events as they happen, not just after the fact." ...

Scientists may have figured out what caused one of the strangest explosions ever observed in our universe: A massive star ...

“Our analysis shows that the blast was sparked by a catastrophic encounter with a black hole companion, and is the strongest evidence to date that such close interactions can actually detonate a star, ...

Another comparison; the Sun is 8.3 light-minutes away, meaning whenever we look at it (not that we should!), we're viewing it ...
