Black Holes

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.

Next time the Event Horizon Telescope turns to study the monster black hole at the center of the Milky Way, it will have help from the James Webb Space Telescope.

A newly discovered black hole with a mass 3 billion times that of the sun is growing by rapidly consuming matter and has powered the most luminous quasar for 9 billion years.

A rogue black hole wandering the space lanes of our Milky Way galaxy alone could be the smallest black hole yet found.

NASA's James Webb Space Telescope is gearing up to start operations this summer, and one of its many assignments will be to search for primeval black holes in the early universe.

Russia wants to restart a German black-hole searching telescope aboard a Russian satellite; the telescope was mothballed on German orders in response to Russia's invasion of Ukraine.

A study of a sample of galaxies that existed up to 12.5 billion years ago has provided further evidence that radiation from active supermassive black holes suppresses star formation.

By employing a new technique to make it easier to see faint gas next to the brilliant glare of a quasar, astronomers have discovered that the quasar is ionizing vast amounts of gas.
