Why they're black: Their gravitational pull is so extreme that even light can't escape Black holes are places where gravity is so powerful that nothing — not even light — can escape. Rather than being ...
Black holes are so strange that physicists have long wondered if they are quite what they seem. Now we are set to find out if ...
A hundred years before the Event Horizon Telescope Collaboration released the first image of a black hole in 2019—located at the heart of the galaxy M87—astronomer Heber Curtis had already discovered ...
When two black holes meet, they are drawn to one another by way of their enormous gravity, initiating a powerful orbital ...
Scientists have begun to unravel the origin story of a cataclysmic collision between two black holes, which seem to have met their fate on a rarely observed "squashed" orbital path.
In May 2019, astronomers picked up something strange in the fabric of spacetime. The LIGO and Virgo detectors recorded a gravitational wave that lasted just one-tenth of a second. The signal, known as ...
Binary black hole systems are turning out to produce some of the most important data in modern astronomy. Credit: NASA's Goddard Space Flight Center A new study in the scientific journal Nuclear ...
Quantum gravity remains one of the big missing pieces of a Grand Unified Theory that could bridge quantum field theory and general relativity. Knowing that quantum gravity solutions must resemble ...
SXS—Simulating eXtreme Spacetimes—is an ongoing scientific collaboration that has been generating simulations of dramatic ...

Astronomers detect radio signals from a black hole tearing apart a star—outside a galactic center
An international team of astronomers has discovered the first tidal disruption event (TDE) producing bright radio emission ...
A tiny fraction of known black holes emit X-ray signals that resemble a human "heartbeat." Now, new research may finally explain the strange phenomenon. Stars that wander too close to supermassive ...
A new study helps solve the "final parsec problem" that has made supermassive black hole formation impossible to explain, pointing to a strange form of dark matter as the key. Black hole growth is ...
