The James Webb Space Telescope captured amazing imagery of merging galaxies II ZW 96. The merger is located 500 million light-years from Earth in the constellation Delphinus. Credit: ESA/Webb, NASA, ...

Scientists have named newly detected merging supermassive black holes after ’Lord of the Rings’ locations, using gravitational wave data and quasar observations to map their mergers.

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

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 ...

For nearly a century, astronomers have known that the universe is expanding. Most galaxies are carried outward with the flow ...

For a single supermassive black hole, extremely strong lensing occurs only when a star lies almost exactly along the line of ...

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

New radio observations of molecular gas reveal how dozens of galaxies could have rapidly merged together in the early Universe.

They found evidence that a giant elliptical galaxy may form through the rapid collapse of this infant galaxy cluster.
