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.
Other examples of quasars with large estimated black hole masses are the hyperluminous quasar APM 08279+5255, with an estimated mass of 1 × 10 10 (10 billion) M ☉, [109] and the quasar SMSS J215728.21-360215.1, with a mass of (3.4 ± 0.6) × 10 10 (34 billion) M ☉, or nearly 10,000 times the mass of the black hole at the Milky Way's ...
A view of M87* black hole in polarised light Sagittarius A*, black hole in the center of the Milky Way. The Event Horizon Telescope (EHT) is an active program that directly observes the immediate environment of black holes' event horizons, such as the black hole at the centre of the Milky Way. In April 2017, EHT began observing the black hole ...
Astronomers have at long last seen the center of the Milky Way galaxy, unmasking a giant black hole, a celestial vortex 26,000 light-years from Earth that should otherwise be hidden from sight.An ...
STORY: Scientists on Thursday provided the first look at a black hole - one they called the "gentle giant" - lurking at the center of the Milky Way."...Sagittarius A*.”The supermassive ...
Black holes are extraordinarily dense objects with grav. At the center of the Milky Way galaxy resides a supermassive black hole four million times the mass of our sun called Sagittarius A* that ...
The Galactic Center is the barycenter of the Milky Way and a corresponding point on the rotational axis of the galaxy. [1] [2] Its central massive object is a supermassive black hole of about 4 million solar masses, which is called Sagittarius A*, [3] [4] [5] a compact radio source which is almost exactly at the galactic rotational center.
Astronomers have discovered a black hole with a mass about 33 times greater than that of our sun, the biggest one known in the Milky Way aside from the supermassive black hole lurking at the ...
