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.
OJ 287 core black holes — a BL Lac object with a candidate binary supermassive black hole core system [23] PG 1302-102 – the first binary-cored quasar — a pair of supermassive black holes at the core of this quasar [24] [25] SDSS J120136.02+300305.5 core black holes — a pair of supermassive black holes at the centre of this galaxy [26]
SMSS J215728.21-360215.1, commonly known as J2157-3602, is one of the fastest growing black holes and one of the most powerful quasars known to exist as of 2021.The quasar is located at redshift 4.75, [1] corresponding to a comoving distance of 2.5 × 10 10 ly from Earth and to a light-travel distance of 1.25 × 10 10 ly.

Astronomers have found the most massive stellar black hole known in our own galaxy. The object is relatively close by, at least in black hole terms, sitting just 2,000 light years away.
There is a natural upper limit to how large supermassive black holes can grow. Supermassive black holes in any quasar or active galactic nucleus (AGN) appear to have a theoretical upper limit of physically around 50 billion M ☉ for typical parameters, as anything above this slows growth down to a crawl (the slowdown tends to start around 10 ...
When astronomers survey the vast expanse of the cosmos, they primarily stumble across two types of black holes.The first is a stellar-mass black hole—formed from the collapse of a star, these ...
It also explains the intense bright shine of galactic molecular clouds around the black hole – scientists say they are reflecting those X-rays that came out of the black hole towards the start ...
