The Phoenix Cluster (SPT-CL J2344-4243) is a massive, Abell class type I galaxy cluster located at its namesake, southern constellation of Phoenix.It was initially detected in 2010 during a 2,500 square degree survey of the southern sky using the Sunyaev–Zeldovich effect by the South Pole Telescope collaboration.

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.

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.
A disk of hot gas swirls around a black hole in this illustration. The stream of gas stretching to the right is what remains of a star that was pulled apart by the black hole.
In this map of the Observable Universe, objects appear enlarged to show their shape. From left to right celestial bodies are arranged according to their proximity to the Earth. This horizontal (distance to Earth) scale is logarithmic.
Our universe: In 'groundbreaking' study, astronomers detect record number of stars in distant galaxy Black hole first observed acting strangely in 2018. The black hole, the official name of which ...
Astronomers have discovered what may be the brightest object in the universe, a quasar with a black hole at its heart growing so fast that it swallows the equivalent of a sun a day. The black hole ...
