A newly identified quasar shows sustained growth beyond the Eddington limit, prompting new examination of accretion physics, radiation trapping and jet activity in early supermassive black holes.

An early black hole feeds too fast—yet still blasts X-rays and radio jets.

The formation of planets is a fascinating process. They usually originate in a disc of dust and gas surrounding stars. When particles come together, they form a clump, and through a process called ...

Astronomers have captured an actively feeding supermassive black hole in the early universe. The black hole was captured during a remarkable growth spurt.
