60-Second Astro News: Black Hole Hubbub
The Milky Way's black hole' flares unexpectedly, a distant black hole gets the hiccups, and a reanalysis of LIGO data shows the first detection of black hole "ringdown."
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.
Gravitational-wave Detectors Come Online, Find Possible Black Hole-Neutron Star Crash
Only a month into a new observing run, gravitational-wave observatories have announced five new signals — one of which could turn out to be a black hole swallowing a neutron star.
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.
Scientists Unveil First Black Hole Image
The Event Horizon Telescope collaboration has reconstructed the shadow of a supermassive black hole.

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 Discover Most Distant Lensed Quasar
The most distant magnified quasar known promises to shed light on the universe's early years.
How “Light Echoes” Revealed a Black Hole’s Feeding Habits
Astronomers are taking a cue from bats, using a method similar to echolocation to map out the feeding environment around a 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.

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.
Gravitational-Wave Observatories Bag Four Black-Hole Collisions
A re-analysis of data from LIGO and Virgo brings the number of gravitational-wave detections to 11, including the most distant and most powerful black-hole merger yet discovered.
A Black Hole X-Ray Binary Rises
New observations have captured a feeding black hole in our galaxy as it bursts onto the scene.
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.

Video: The Glow of Spiraling Black Holes
New calculations reveal what two supermassive black holes about to merge would look like in ultraviolet and X-rays.
Middleweight Black Holes Provide Window to Early Universe
How did supermassive black holes form? Two studies discovered dozens of middling-mass black holes in dwarf galaxies to fuel an ongoing debate.
A Rapidly Spinning Black Hole with a Warped Disk
An X-ray telescope recently installed on the International Space Station has provided a detailed look at a black hole feeding off its companion star.
Star Swings Around Black Hole, Tests Gravity
Astronomers have seen a star’s light redden as it passed our galaxy’s central black hole, just as general relativity predicts.
