Quasars are extraordinarily bright regions surrounding supermassive black holes, where infalling gas and dust generate enormous energy.

For the first time, astronomers have managed to capture a radio image showing two black holes orbiting each other. The ...

A black hole in a distant quasar is growing faster than the usual limit, according to Chandra observations. This may explain ...

Astronomers have captured the first radio image of two supermassive black holes orbiting each other within the quasar OJ287, ...

The first-ever sighting of starlight from a galaxy hosting one of the most distant quasars known has revealed an astronomical oddity. Quasars — blazingly bright galactic cores — owe their brilliance ...

Astronomers have successfully captured an image of two black holes orbiting each other, confirming they can exist in pairs.

Astronomers have detected an intensely brightening and dimming quasar that may help explain how some objects in the early universe grew at a highly accelerated rate. The discovery is the most distant ...
