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.
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
MS 0735.6+7421 is a galaxy cluster located in the constellation Camelopardalis, approximately 2.6 billion light-years away.It is notable as the location of one of the largest central galactic black holes in the known universe, which has also apparently produced one of the most powerful active galactic nucleus eruptions discovered.
The black hole, the official name of which is a mouthful (1ES 1927+654), is located in the distant constellation Draco.
A photograph of a black hole at the center of galaxy M87. The black hole is outlined by emission from hot gas swirling around it under the influence of strong gravity near its event horizon.
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]
ULAS J1342+0928 is the third-most distant known quasar detected and contains the second-most distant and oldest known supermassive black hole, [1] [5] [6] [7] at a reported redshift of z = 7.54. The ULAS J1342+0928 quasar is located in the Boötes constellation . [ 3 ]
The supermassive black hole Sagittarius A*, imaged by the Event Horizon Telescope [8] Astronomers now have evidence that there is a supermassive black hole at the center of the galaxy. [ 9 ] Sagittarius A* (abbreviated Sgr A*) is agreed to be the most plausible candidate for the location of this supermassive black hole.
