Astronomers have used the death of a star to uncover details about a hidden intermediate-mass black hole.
60-second Astro News: White Dwarfs Still Burn, Black Holes Merge
This week in astronomy news, we learn that some white dwarfs still burn and image X-rays from black holes almost 12 billion light-years away.
Watch Black Holes Grow, Galaxies Fall
Watch black holes grow and galaxies fall — astro photos and visualizations to get you through the week.

Event Horizon Telescope Reveals Curious Jet Structure from Black Hole
Observations of the nearest radio galaxy, Centaurus A, provide the highest-resolution look at the long jets shooting from the galaxy’s supermassive black hole.
Gravitational Waves Reveal Black Hole–Neutron Star Mergers
Two new detections give astrophysicists a novel look at how stellar remnants pair up.
From Starving Black Holes to Warped Galaxies
Hot topics from the American Astronomical Society summer meeting range from colliding galaxies, to warped galaxies, to starving black holes.
Astronomy in Pictures: Unraveling Galaxies and Clyde's Spot
This week in astronomy pictures: Peer into our galaxy's busy core, watch Clyde's Spot unravel at Jupiter, and see a stunning Hubble photo of a lopsided galaxy.
Jumping the Gap to Probe Large Black Holes
Gravitational-wave detectors should be able to locate a population of huge black holes soon. A new study predicts when we'll find them, and what they'll teach us.
Is the “Unicorn” the Closest Black Hole?
Astronomers again think they have found the black hole nearest to us, just 1,500 light-years away, but the find still needs to be confirmed.
Redefining a Heavy Collision
Could the biggest — literally — gravitational-wave discovery yet be something other than what it initially seemed?
Flares from the Milky Way’s Supermassive Black Hole
The supermassive black hole at the center of the Milky Way released an unusual number of strong flares in 2019. Now, astronomers are trying to figure out why.

Astronomers Detect Strong Magnetic Fields Around M87’s Black Hole
Event Horizon Telescope data support the idea that magnetic fields control how black holes feed and grow.
A Supermassive Black Hole on the Move
This supermassive black hole is restless, and astronomers want to know why.
Star-shredding Black Hole Makes Ghostlike Particle
A single high-energy neutrino may shed light on a star being swallowed by a supermassive black hole some 690 million light-years away.
First-detected Black Hole is More Massive Than We Thought
A higher mass for Cygnus X-1, the first black hole to be discovered, challenges ideas about the evolution of massive stars.
Astronomy News: Galactic One-Two Punch, Black Hole Heartbeat Falters
In the news this week: Globular clusters have the detailed scoop on our galaxy's past, and a "heartbeat" black hole binary in the Milky Way has gone mysteriously dim.
What the Most Distant Quasar Tells Us About Black Hole Birth
The existence of a quasar when the universe was only 670 million years old is helping astronomers understand how black holes are born.
Black Hole Feasts on Star, Bite by Bite
Like a cosmic blinker, a distant supermassive black hole is flaring every 114 days. Astronomers believe the eerily regular signal betrays the piecemeal devouring of a star.
Pulsars Show Hint of Gravitational-wave Background
Duos of supermassive black holes tangoing throughout the universe make their own music, and astronomers may have picked up a hint of the tune.
