Black Holes Grow by Gas, Not Mergers, Most of Their Lives
Calculations suggest how black holes have amassed mass and predict what the black holes’ spins should be if this picture is correct.

Closest Black Hole to Earth? Maybe
An international team of astronomers says that they’ve discovered the closest black hole to Earth — an invisible object dancing with two large, bright stars 1,000 light-years away.

Mismatched Black Holes Merge
For the first time, the LIGO and Virgo gravitational-wave detectors have "heard" gravitational waves from an unequal pair of black holes.

Black Hole Changes Star’s Orbit in Gravity Test
A long-awaited measurement indicates that a star whizzing around the Milky Way’s supermassive black hole has changed its trajectory.

Event Horizon Telescope Finds Bent Jet Near Black Hole
Observations from the worldwide network of radio telescopes show the fire hose of plasma shooting from a distant galaxy does something strange near its source.

Scientists Predict Countless Rings of Light Encircle Black Holes
Detailed calculations reveal a surprise about how black holes bend light around themselves, opening a new possibility for future observations.

More Big Black Holes Found in Small Galaxies
In the quest to discover how massive black holes form, astronomers have spotted several of these objects in some of the smallest galaxies yet found to host them.

Bubbles, Heated Clouds Point to Active Past for Galactic Center
Two studies support the suspicion that our galaxy’s black hole had one or more outbursts a few million years ago.

More Black Hole Mergers Found in LIGO Data
Analysis by an independent team has ferreted out seven candidates for gravitational-wave events from merging black holes.

Video: Black Hole Warps Light
The hypnotizing effect of a black hole on its surroundings appears to dramatic effect in this simulation.

Galactic Center Gravity Test Confirmed
A second team of astronomers has now confirmed the light from a star passing near our galaxy’s central black hole behaved as predicted by Einstein’s theory of gravity.

How Does the Event Horizon Telescope Work?
The Event Horizon Telescope creates the image of a black hole shadow thanks to the precise coordination of a worldwide telescope network. Here’s how they do it.

Could Dark Matter Be Black Holes?
Astronomers are reconsidering primordial black holes as an answer to the invisible matter mystery, but recent observations disfavor at least some sizes of black hole.

Piercing the Veil of Our Black Hole
Astronomers have overcome the interference of clumpy interstellar gas to catch a glimpse of the gas around the Milky Way’s central black hole.

Astronomers Use Annihilated Star to Clock Black Hole’s Spin
The glow of a star torn up by a supermassive black hole has enabled researchers to measure how fast the black hole whirls around.

Rotating Gas in a Quasar’s Heart
Astronomers have “imaged” gas as it orbits a supermassive black hole some 2 billion light-years away.

What LIGO Teaches Us About Black Holes
The rising count of gravitational-wave events is giving us a new look at a once-invisible population of black holes.

Gas Seen Moving Near the Event Horizon
Astronomers have detected three flares from near our galaxy’s central black hole that look like gas closely orbiting the unseen object.

Odd Jets Might Signal Dual Black Holes
Off-kilter, curved, and otherwise unusual beams of plasma from galaxies’ cores might track the dueling dances of two supermassive black holes.
