Black Holes

Plumes of hot gas and charged particles emitted by black holes drift across distances of hundreds of thousands of light years.

Black holes exert small amounts of pressure on their environment a new study finds, hinting at a more complex nature of these mysterious objects.

There comes a time in every galaxy's life, astronomers think, when the galaxy ejects a large part of its gas, but scientists aren't certain what drives this "mid-life crisis."

Astronomers have uncovered evidence of explosions triggered by dead stars ramming into live stars, possible proof of a new type of supernova, a new study finds.

What are the chances that a primordial black hole forged in the earliest moments of the universe will come wandering toward Earth?

There's no consensus yet on how supermassive black holes form, but a new mesmerizing simulation is taking a crack at that question like never before.

A new simulation predicts that the lost giants were dislodged by gigantic collisions and have wandered the outskirts of galaxies ever since.

Black holes may sound like science fiction, but there is significant evidence to prove they are real.

Certain weird gravity conditions would make it possible to travel through a wormhole and back.

The most detailed radio images of galaxies outside the Milky Way have been captured by a network of 70,000 radio antennas spread over nine European countries.

Astronomers think they have established a new way to calculate the size of supermassive black holes: by studying the feeding patterns of these invisible giants.

Concentric ripples in galactic dust clouds triggered by a powerful black-hole X-ray burst can be seen in a new image released by NASA.

Astronomers have imaged an extraordinary black hole picnic of cosmic proportions.

For the first time ever, scientists have seen the light "echoing" from behind a black hole.

A German X-ray mission is mapping the distribution of black holes and neutron stars in the Universe, having discovered over two million such new objects in less than two years since its launch.

New images obtained by the Event Horizon Telescope (EHT) reveal a powerful jet ejected from a supermassive black hole in unprecedented detail.

Theories that attempt to resolve the so-called black hole information paradox predict that black holes are much more complicated than general relativity suggests.

Scientists hunting for elusive gravitational waves across the universe may be able to supercharge their discoveries with a new tool: artificial intelligence.

A cluster composed of thousands of stars may dissolve to become a mob of dozens of black holes in a billion years.
