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.

Astronomers from Swinburne University of Technology, Australia, and the University of Minnesota Duluth, USA, have provided a way for armchair astronomers, and even primary school children, to merely look at a spiral galaxy and estimate the mass of its hidden, central black hole.

Scientists at the University of Nottingham have made a significant leap forward in understanding the workings of one of the mysteries of the universe.

A long-standing question in astrophysics is: how and when did supermassive black holes appear and grow in the early universe?

Astronomers have watched as a massive, dying star was likely reborn as a black hole.

Pointing the Very Large Array (VLA) at a famous galaxy for the first time in two decades, a team of astronomers got a big surprise, finding that a bright new object had appeared near the galaxy's core.
