Before LIGO's detections, astronomers only had definitive observations of two varieties of black holes: ones that form from stars that were thought to top out around 20 solar masses; and, at the cores of large galaxies, supermassive black holes of still - uncertain provenance containing millions or billions of times the mass of the sun.

They form when a large galaxy's gravity pulls one edge of a nearby satellite galaxy more strongly than the other edge, unraveling the galaxy and leaving stars behind.
We go out into the interstellar medium, this is the gas between the stars like the sun, that too is mostly plasma — not all of it, some of it is in the form of neutral gas, but a large fraction of it is in the form of plasma — and then if we go outside the galaxy itself, into the space between the galaxies, the so - called intergalactic space, then again, that is mostly plasma.
