Supermassive black holes rarely travel alone. Most large galaxies hide one at the center, and when galaxies collide, the two ...

Supermassive black hole binaries form naturally when galaxies merge, but scientists have only confidently observed a very few of these systems that are widely separated. Black hole binaries that ...

Researchers propose a new technique to identify supermassive black hole binaries through gravitational lensing causing ...

When you buy through links on our articles, Future and its syndication partners may earn a commission. A view of The Cosmic Horseshoe and its gravitational lens, in which an ultramassive black hole ...

Scientists believe that when galaxies collide and merge, the supermassive black holes at their centers should eventually pair ...

Forbes contributors publish independent expert analyses and insights. An award-winning reporter writing about stargazing and the night sky. Astronomers have detected what may be the most massive black ...

Black holes continue to grip our imagination. These cosmic powerhouses twist space and time so intensely that even light cannot escape once it crosses a certain boundary. Their defining edge—the event ...

Astronomers have discovered potentially the most massive black hole ever detected. The cosmic behemoth is close to the theoretical upper limit of what is possible in the universe and is 10,000 times ...

The Cosmic Horseshoe gravitational lens. The newly discovered ultramassive blackhole lies at the centre of the orange galaxy. Far behind it is a blue galaxy that is being warped into the horseshoe ...

Scientists have developed a new method to spot hidden supermassive black hole binaries using gravitational lensing. Orbiting pairs of binary black holes should produce repeating flashes of lensed ...

Astronomers examining data from the James Webb Space Telescope say they’ve spotted what might be the oldest black hole in the universe, born less than a second after the Big Bang. Their findings, ...
