Black Holes

Scientists are uncovering how mysterious medium-sized black holes may arise from collisions of massive stars.

Scientists have spotted a cluster of rapidly growing black holes that offer a glimpse at something called "cosmic noon."

NASA's Hubble Space Telescope has captured a stunning new view of a galaxy with an active black hole obscured by tendrils of dark dust.

A seemingly intractable black hole paradox first proposed by physicist Stephen Hawking could finally be resolved — by wormholes through space-time.

Though scientists know there's a supermassive black hole at the center of most galaxies, they can't explain how the gravitational giants formed.

If you've ever been stuck in a nightmare traffic jam, you know that "black hole from which you can never escape" captures the feeling well.

The planet-scale array of observatories most famous for creating the first-ever image of a black hole is heading back to work.

Albert Einstein saw beyond human tribalism to an enlightened realm of tolerance. We can too: He left us clear directions for how to do it.

Take three black holes and throw them into the disk surrounding a supermassive black hole and things get really weird, really fast.

Two giant bubbles of gamma rays and X-rays that erupted from the center of the Milky Way may stem from a supermassive black hole's feeding frenzy at the heart of the galaxy, a new study finds.

Germany stopped all science cooperation with Russia over its Ukraine invasion, but space station work continues.

In a paper published today, an international team of researchers has disproved the existence of a black hole in HR 6819.

A new study shows two huge black holes locked in each other's gravity as they inevitably spiral towards a collision.

White holes are really just something scientists have imagined — they could exist, but we’ve never seen one, or even seen clues that one may exist.

A tilted black hole spinning around a misaligned axis has been discovered in our galaxy, challenging theories of black hole formation.

Scientists are using quantum computing to understand what's inside a black hole and test if our universe is a holographic projection.

A supermassive black hole masked by a cloud of cosmic dust was found at the center of an active galaxy in new images from the European Southern Observatory.

A new museum exhibit hopes to uncover the secrets behind the doodles, in-jokes and coded messages on a blackboard that Stephen Hawking kept for more than 35 years.

Astronomers may have for the first time detected and measured the mass of an isolated stellar-mass black hole, a new study finds.
