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.
Astronomers believe that one of its components, known as Sagittarius A*, is associated with a supermassive black hole at the center of the galaxy, with a mass of 2.6 million solar masses. [24] Although not visible to the naked eye, Sagittarius A* is located off the top of the spout of the Teapot asterism. [ 1 ]
The supermassive black hole Sagittarius A*, imaged by the Event Horizon Telescope [11] Astronomers now have evidence that there is a supermassive black hole at the center of the galaxy. [12] Sagittarius A* (abbreviated Sgr A*) is agreed to be the most plausible candidate for the location of this supermassive black hole.
The first image of the black hole at the center of the Milky Way galaxy, named Sagittarius A*, has been captured by NASA's Event Horizon Telescope.
The famous first picture of the supermassive black hole at the heart of our galaxy might not be accurate, a new study has claimed. The picture – initially published in 2022, after years of ...
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 ...
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 ...
