This is a list of lists of black holes: List of black holes; List of most massive black holes; List of nearest known black holes; List of quasars; See also.
The supermassive black hole at the core of Messier 87, here shown by an image by the Event Horizon Telescope, is among the black holes in this list. This is an ordered list of the most massive black holes so far discovered (and probable candidates), measured in units of solar masses ( M ☉ ), approximately 2 × 10 30 kilograms .
Sagittarius A*, abbreviated as Sgr A* (/ ˈ s æ dʒ ˈ eɪ s t ɑːr / SADGE-AY-star [3]), is the supermassive black hole [4] [5] [6] at the Galactic Center of the Milky Way.Viewed from Earth, it is located near the border of the constellations Sagittarius and Scorpius, about 5.6° south of the ecliptic, [7] visually close to the Butterfly Cluster (M6) and Lambda Scorpii.
The conventional wisdom among astronomers is that black holes - those exceptionally dense objects with gravity so powerful that not even light can escape - form in the violent explosion, called a ...

Size comparison of the event horizons of the black holes of TON 618 and Phoenix A.The orbit of Neptune (white oval) is included for comparison. As a quasar, TON 618 is believed to be the active galactic nucleus at the center of a galaxy, the engine of which is a supermassive black hole feeding on intensely hot gas and matter in an accretion disc.
There's also a theory that there is a portal to another dimension and another that says there's a black hole there. Click below for some of the best photos on NASA's Instagram:
