Black Holes

Black holes have properties characteristic of quantum particles, a new study reveals, suggesting that the puzzling cosmic objects can be at the same time heavy and light.

Dozens of telescopes all over the world are pointing at a patch of sky that gave rise to the most powerful gamma-ray burst ever seen, hoping to shed more light on processes that birth black holes.

A black hole at the heart of a distant galaxy is blasting a neighboring galaxy with a jet of plasma moving at near light speed.

A monster merger between two black holes sent ripples through time and space, and may prove Einstein right about a gravitational phenomenon called precession.

A black hole is burping out the remnants of a star it ripped apart and ate years ago in a type of tidal disruption event that is like nothing astronomers have ever seen.

NASA's iconic new observatory has spotted surprising compounds around supermassive black holes.

Black holes go boom in several ways.

Astronomers have spotted a hot spot orbiting Sagittarius A* that could be a gas bubble traveling at around 30% the speed of light.

Spanning more than a million light years from end to end, the jet shoots away from a black hole with enormous energy, and at almost the speed of light.

A small galaxy swallowed by a larger spiral galaxy deposited a supermassive black hole as it was violently ripped apart and consumed.

New research suggests that the expansion of the universe could be measured using colliding black holes as 'spectral sirens.'

The golden glowing ring of matter seen in the first-ever image of a black hole has been remastered, revealing the action of gravity around such cosmic titans.

A powerful and spectacular cosmic dance that began a billion years ago will lead to a collision and merger between two galaxies and the supermassive black holes at their hearts.

Scientists think that when dark photons collect around black holes, they can get trapped and boosted to high energies, where they might transform into other particles (or even just normal photons).

Astronomers hope to use pulsars scattered around the galaxy as a giant gravitational wave detector. But why do we need them, and how do they work?

The Event Horizon Telescope has imaged the powerful near-light-speed jet of a blazar, and found it to be twisted.

New research suggests a way for black holes to merge quickly: They must be caught in the accretion disk of a supermassive companion.

The European Space Agency is considering ways to redesign a major X-ray space telescope after a number of ESA member states have backed out of the project.

The origins of high-energy particles that bombard the Earth from deep space may have been revealed for the first time by new research.

Even NASA's newest observatory can't manage to see supermassive black holes directly, but that doesn't mean astronomers can't use its data to better understand the mysterious behemoths.
