Black Holes

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.

A cosmic crime scene has revealed the gory details of black holes' eating habits.

New research motivated by string theory suggests possible, and equally strange, fates for evaporating black holes.

Astronomers have found a binary system containing a massive blue star and a dormant stellar-mass black hole in the star-forming Tarantula Nebula of the Large Magellanic Cloud.

Researchers found that streams of cold gas could create 'seeds' of quasars — ultraluminous supermassive black holes — in the early universe, solving a decades-old mystery.

Scientists have measured how fast a supermassive black hole is spinning, and the result might give us a clue about how the giant formed.

Following two years of upgrades, the Laser Interferometer Gravitational-Wave Observatory (LIGO) is almost ready for its next operating run, which is set to begin in March 2023.

Study reveals why mysterious gamma-ray bursts appear to blink and suggests that these mysterious phenomena might be much rarer than astronomers thought.
