Heavyweight Black Hole Find Mystifies Astronomers
Observations of a star have found it orbiting an unexpectedly massive black hole. If the discovery pans out, it would change our understanding of how massive stars die.
Three Black Holes May Merge in Nearby Galaxy
New observations of a galactic crash site show that there are not just two but three supermassive black holes on the verge of union. Two of them are only 650 light-years apart, the closest pair known.

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.
Exoplanet Hunter Sees a Black Hole-Shredded Star
NASA's TESS exoplanet-hunting satellite has provided astronomers with a front-row seat as a black hole shreds a close-venturing star.
Video: Black Hole Warps Light
The hypnotizing effect of a black hole on its surroundings appears to dramatic effect in this simulation.
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.

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.
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.
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.
