The main light source from a black hole is a structure called an accretion disk. Black holes grow by consuming matter, a process scientists call accretion, and by merging with other black holes. A stellar-mass black hole paired with a star may pull gas from it, and a supermassive black hole does the same from stars that stray too close.

Black holes are among the most mysterious cosmic objects, much studied but not fully understood. These objects aren’t really holes. They’re huge concentrations of matter packed into very tiny spaces.
Scientists use our fleet of telescopes to help us understand objects from our nearest neighbor stars, to monster black holes and distant galaxies. Anatomy of a black hole interactive
8 Σεπ 2020 · A black hole is an astronomical object with a gravitational pull so strong that nothing, not even light, can escape it. A black hole’s “surface,” called its event horizon, defines the boundary where the velocity needed to escape exceeds the speed of light, which is the speed limit of the cosmos.
Basic Black Hole Anatomy Black holes are physical objects in space, just like stars and planets. They have so much mass packed into such a small sphere that nothing, not even light, can escape their gravity. Features all have in common Event horizon: the black hole’s “surface” — the point of no return Spin: how fast depends on the ...
Black holes consist of two main components: the singularity, where mass has been crushed to a point; and the event horizon, beyond which nothing ― not even light ― can escape the black hole’s intense gravitational pull.
