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.

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.

Science Fiction Wormholes Don’t Exist
Hoping for faster-than-light travel? Wormholes aren't the paths you're looking for.
More Mystery Objects in the Galactic Center
Astronomers have discovered three more red, dusty objects near the Milky Way’s central black hole that could be merged stars.
Do Big Black Holes Wander the Galaxy?
New simulation work suggests that galaxies like the Milky Way could be home to a dozen supermassive black holes.
Most Distant Black Hole Yet
Astronomers have discovered a supermassive black hole scarfing down gas just 690 million years after the Big Bang.

Infant Stars Huddle near Black Hole
A team of astronomers has found signs of small stars forming within a few light-years of the Milky Way’s central black hole.
LIGO Sees Smallest Black Hole Binary Yet
LIGO has detected another black hole merger, raising the tally to five.
First Black Holes Maybe Had Supersonic Help
Gas flows in the early universe may have kept clouds from collapsing too soon, enabling them to grow into massive black hole seeds.

LIGO Detects Third Black Hole Merger
Scientists with the gravitational-wave observatory announce another discovery, this time of a black hole merger twice as far away as previous detections.
What’s Inside a Black Hole?
What’s inside a black hole? Wormholes? Alternate universes? If you fell into a black hole, only one thing’s for sure: its tidal forces would kill you.
