Black Hole
What are supermassive black holes, how common are they, and how do they grow up throughout cosmic history? Listen and find out!
From the present day all the way to less than 400 million years after the Big Bang, we're seeing how the Universe grew up like never before.
Some 55 million light-years away lies the giant galaxy Messier 87. Its supermassive black hole, inside and out, looks better than ever.
After 15 years of monitoring 68 objects known as millisecond pulsars, we've found the Universe's background gravitational wave signal!
In a distant galaxy, a cosmic dance between two supermassive black holes emits periodic flashes of light.
The brightest gamma-ray burst ever observed, GRB 221009A behaved in unexpected ways that might help us understand how they occur.
There are 40 billion billion black holes in the universe. Here’s how our Solar System stacks up against ten of them.
When Einstein gave General Relativity to the world, he included an extraneous cosmological constant. How did his 'biggest blunder' occur?
In 1974, Hawking showed that black holes aren't stable, but emit radiation and decay. Nearly 50 years later, it isn't just for black holes.

Sabine Hossenfelder talks about Albert Einstein, dead grandmothers, the physics of aging, and more in this full interview with Big Think.
Massive objects like black holes, stars, and rogue planets routinely pass near our Solar System. An ensuing comet storm could destroy us.
The odds are slim, but the consequences would be literally world-ending. There really is a chance of a black hole devouring the Earth.
Though he renounced philosophy, Stephen Hawking's final theory of the universe redraws the basic foundations of cosmology.
Stars orbiting black holes were observed to move significantly slower than expected. One explanation centers on dark matter.
Leading a scientific revolution is easy: you just have to succeed where the current theory fails while equaling its successes. Good luck!
Gamma-ray bursts are among the most energetic cosmic events of all. On October 9, 2022, a remarkable one occurred: the brightest ever seen.
What do we mean by a black hole's size? A photon sphere? The minimal stable orbit? The event horizon? The singularity? Which one is right?
Speeding through the Universe and leaving a wake of new stars, this runaway supermassive black hole is likely the first among thousands.
This beautiful JWST image of Wolf-Rayet star WR 124 has been called a "prelude to a supernova" by NASA. That might be entirely wrong.
When supermassive black holes merge, they emit more energy than anything else to occur in our Universe except the Big Bang.
We can't go back to the Big Bang, nor ahead to the heat death of the Universe. Nevertheless, here are today's natural temperature extremes.
Somewhere out there in the Universe is the heaviest neutron star, and elsewhere lies the lightest black hole. Where's the line between them?
Two very different ideas, wormholes and quantum entanglement, might be fundamentally related. What would "ER = EPR" mean for our Universe?
What kind of object will you form? What will its fate be? How long will a star live? Almost everything is determined by mass alone.
JWST's revolutionary views arrive in high-resolution at infrared wavelengths. Without NASA's Spitzer first, it wouldn't have been possible.
An incredible composite image of Pandora's Cluster, Abell 2744, simultaneously showcases both our impressive knowledge and vast ignorance.
Since its observation discovery in the 1990s, dark energy has been one of science's biggest mysteries. Could black holes be the cause?
In general relativity, white holes are just as mathematically plausible as black holes. Black holes are real; what about white holes?
In just a few seconds, a gamma-ray burst blasts out the same amount of energy that the Sun will radiate throughout its entire life.
