Astronomers are taking a cue from bats, using a method similar to echolocation to map out the feeding environment around a black hole.
The glow of a star torn up by a supermassive black hole has enabled researchers to measure how fast the black hole whirls around.
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.
How did supermassive black holes form? Two studies discovered dozens of middling-mass black holes in dwarf galaxies to fuel an ongoing debate.
New observations give more fuel to the concept of intermediate-mass black holes.
A new study has uncovered a dozen stellar-mass black holes within 3 light-years of the supermassive black hole at our galaxy’s core — and these might be just the tip of the iceberg.
