SUNSET: 
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.
The Appearance of a Black Hole’s Shadow
In April of this year, the Event Horizon Telescope captured the first detailed images of the shadow of a black hole. In a new study, a team of scientists has now explored what determines the size and shape of black hole shadows like this one.
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.
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.
