Sentences with phrase «environment around a black hole»

The black holes that we can observe directly through their radiant emission are mostly in a configuration where gas swirls around the black hole in the form of an accretion disk and that accretion disk — most of the mass is going to be in an ionized form, and then some of that gas gets expelled from the environment around the black hole, while it is still outside the black hole, it gets squirted out in the form of an outflow, a wind like the solar wind and then [a] much faster, collimated outflow called a jet.
