This is visible whenever there is a direct view of the accretion disc.

It is usually caused by the dynamic interactions within an accretion disc.

The red giant is transferring material onto an accretion disc around a smaller star.

In the central glare of the accretion disc, there was something surrounding the black hole, embedding it.

A pillar of radiation punched through the accretion disc like a fist.

A forming star is often surrounded by accretion disc in their first few hundred thousand years of existence.

This type of accretion disc was predicted in 1977 by Ichimaru.

"If it's a hole it has no accretion disc," Malenfant said.

It requires an accretion disc with a strong polar magnetic field around a spinning black hole.

The quasar is powered by an accretion disc around the black hole.
