Scientists observed what appears to be a bulked-up black hole tangling with a more ordinary one.

They are billions of times larger than our Sun: how is it possible that, as recently observed, supermassive black holes were already present when the Universe, now 14 billion years old, was "just" 800 million years old?

Planets Around A Black Hole?

Theoreticians in two different fields defied the common knowledge that planets orbit stars like the Sun. They proposed the possibility of thousands of planets around a supermassive black hole.

Some relationships are written in the stars. That's definitely the case for supermassive black holes and their host galaxies, according to a new study from Yale University.

An international team of astrophysicists from Southampton, Oxford and South Africa have detected a very hot, dense outflowing wind close to a black hole at least 25,000 light-years from Earth.

Astronomers have just managed to take the first image of a black hole, and now the next challenge facing them is how to take even sharper images, so that Einstein's Theory of General Relativity can be tested.

A team of astronomers has discovered 83 quasars powered by supermassive black holes (SMBHs) in the early universe.

How To Escape A Black Hole

Black holes are known for their voracious appetites, binging on matter with such ferocity that not even light can escape once it's swallowed up.

Based on computer simulations and new observations from the Atacama Large Millimeter/submillimeter Array (ALMA), researchers have found that the rings of gas surrounding active supermassive black holes are not simple donut shapes.

New research, published Wednesday, 24 October, in the journal Monthly Notices of the Royal Astronomical Society, has found evidence for a large number of double supermassive black holes, likely precursors of gigantic black hole merging events.

Scientists have been able to prove the existence of small black holes and those that are super-massive but the existence of an elusive type of black hole, known as intermediate-mass black holes (IMBHs) is hotly debated.

The historic first detection of gravitational waves from colliding black holes far outside our galaxy opened a new window to understanding the universe.

This black hole bounty consists of stellar-mass black holes, which typically weigh between 5 and 30 times the mass of the Sun.

Astronomers are beginning to understand what happens when black holes get the urge to roam the Milky Way.

On Nov. 11, 2014, a global network of telescopes picked up signals from 300 million light-years away that were created by a tidal disruption flare -- an explosion of electromagnetic energy that occurs when a black hole rips apart a passing star.

The biggest black holes in the universe are growing faster than the rate of stars being formed in their galaxies, according to two new studies using data from NASA's Chandra X-ray Observatory and other telescopes.

The centers of massive galaxies are among the most exotic regions in the universe.

Astronomers using ESO's MUSE instrument on the Very Large Telescope in Chile have discovered a star in the cluster NGC 3201 that is behaving very strangely.

Scientists have solved a cosmic mystery by finding evidence that supermassive black holes prevent stars forming in some smaller galaxies.

Scientists have uncovered a rare relic from the early universe: the farthest known supermassive black hole.
