The idea of black holes was first proposed in 1916, but at the time, physicists didn't think they actually existed. Today, we ...

Astronomers have detected the first X-ray emission from a 'little red dot' (LRD), a rare cosmic object thought to hide a growing supermassive black hole within dense gas. The object, 3DHST-AEGIS-12014 ...

About 450 million light-years from Earth, a supermassive black hole is doing something astronomers have long suspected was ...

Black holes are massive, strange and incredibly powerful astronomical objects. Scientists know that supermassive black holes reside in the centers of most galaxies. But there's an open question in ...

Astronomers have discovered in the Markarian 501 galaxy, located 500 million light-years from Earth, a pair of supermassive ...

Astronomers saw past the blinding light of a quasar, only to find a supermassive black hole that's much smaller than theoretical predictions. Reading time 2 minutes All galaxies have a supermassive ...

For the first time, astronomers have gotten a detailed look at how a supermassive black hole (SMBH) eats, discovering two large spiral arms of gas that are funneling its meals inward. The finding, ...

A supermassive black hole binary system (two black holes orbiting each other) has been directly identified in the final stages of orbital decay in all.

In a significant potential shift for astrophysics, it turns out that some quasars may weigh as little as half what was previously believed. Share on Facebook (opens in a new window) Share on X (opens ...
