Black Hole
In general relativity, white holes are just as mathematically plausible as black holes. Black holes are real; what about white holes?
The center of the galaxy doesn't just host stars and a black hole, but an enormous set of rich gassy and dusty features. Find out more!

“You’re not meant to understand what I just said, because I don’t understand what I just said…” Physicist Brian Cox on one of the most complex theories in space science.
Galaxies don't simply feed their central supermassive black holes, but the activity generated inside affects the entire galaxy and more.

Is information intrinsic in our universe? NASA’s Michelle Thaller explains.
The second law of thermodynamics tells us that entropy always increases. But that doesn't mean it was zero at the start of the Big Bang.
Although many of Einstein's papers revolutionized physics, there's one Einsteinian advance, generally, that towers over all the rest.
Want to avoid getting "spaghettified" by a black hole? Steer clear of the smaller ones.
Today, supermassive black holes and their host galaxies tell a specific story in terms of mass. But JWST reveals a different story early on.
One newly discovered, ancient star has a composition unlike any other. Explaining its existence is already blowing astronomers' minds.
Here's why the answer may forever elude scientists.
As early as we've been able to identify them, the youngest galaxies seem to have large supermassive black holes. Here's how they were made.
The first stars took tens or even hundreds of millions of years to form, and then died in the cosmic blink of an eye. Here's how.
The Universe is an amazing place. Under the incredible, infrared gaze of JWST, it's coming into focus better than ever before.
Thanks to observations of gravitational waves, scientists were able to settle a longstanding debate over the speed of gravity.
Since JWST first glimpsed the Universe, we've entered a new era in understanding the earliest objects in the Universe. What have we learned?
The brilliant mind who discovered the spacetime solution for rotating black holes claims singularities don't physically exist. Is he right?
The Big Bang theory is not threatened, but astrophysicists have some explaining to do.
All matter particles can act as waves, and massless light waves show particle-like behavior. Can gravitational waves also be particle-like?
With JWST, Chandra, and gravitational lensing combined, evidence has emerged for the earliest black hole ever. And wow, is it a surprise!
For the first time, astronomers have created a data-driven estimate for how many black holes are in our Universe: more than anyone expected.

When black holes disappear, what happens to the stuff that fell in? Physicist Brian Cox explains.
From the Big Bang to black holes, singularities are hard to avoid. The math definitely predicts them, but are they truly, physically real?
The hot Big Bang was an energetic, brilliantly luminous event. Today's Universe is alight with stars. But in between, the dark ages ruled.
The matter that creates black holes won't be what comes out when they evaporate. Will the black hole information paradox ever be solved?

Quantum wormholes are mathematically possible — but might also be physically impossible. Physicist Janna Levin explains Hawking’s famous information paradox.

Gravity defies quantum mechanics. What does that mean for a theory of everything?

Ever wonder what would happen if we got sucked into a black hole? Turns out we could live in it for a while — if it was big enough.
Even with the quantum rules governing the Universe, there are limits to what matter can withstand. Beyond that, black holes are unavoidable.
Nothing can escape from a black hole. So where do Hawking radiation, relativistic jets, and X-ray emissions around black holes come from?
