This is a list of known black holes that are close to the Solar System. It is thought that most black holes are solitary, but black holes in binary or larger systems are much easier to detect. [1] Solitary black holes can generally only be detected by measuring their gravitational distortion of the light from more
The images show the Perseus Cluster and the Centaurus Cluster, each with a central black hole appearing as a bright white dot surrounded by patches and filaments of gas.
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.
Now, for the first time, scientists published compelling evidence that they detected one of these rapidly moving, rogue black holes.This type of black hole is created when a star (around 20 times ...
However, only primordial black holes with masses above 10 11 kg would still exist today, as any less massive would have completely evaporated via Hawking radiation by the modern era. [ 31 ] Primordial black holes are plausible dark matter candidates, however arguments based upon their observed abundance cast doubt on their ability to be the ...

Known gravitational wave events come from the merger of two black holes (BH), two neutron stars (NS), or a black hole and a neutron star (BHNS). [ 9 ] [ 10 ] Some objects are in the mass gap between the largest predicted neutron star masses ( Tolman–Oppenheimer–Volkoff limit ) and the smallest known black holes.
GW190521 is a significant discovery due to the masses of the resulting large black hole and of one or both of the smaller constituent black holes. Stellar evolution theory predicts that a star cannot collapse itself into a black hole of more than about 65 M ☉, leaving a black hole mass gap above 65 M ☉. The 85 +21 −14 M ☉ [note 3] and ...
