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.
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.
Evidence indicates that the Milky Way galaxy has a supermassive black hole at its center, 26,000 light-years from the Solar System, in a region called Sagittarius A* [92] because: The star S2 follows an elliptical orbit with a period of 15.2 years and a pericenter (closest distance) of 17 light-hours ( 1.8 × 10 13 m or 120 AU) from the center ...
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 some scientists have called a gentle giant because of its ...
At the heart of our Milky Way galaxy lurks a supermassive black hole about four million times the mass of the sun, called Sagittarius A*. But since NASA's James Webb Space Telescope came online in ...
Supermassive black holes are seen as sources of wanton cosmic destruction, ... (Sagittarius A*, the black hole at the center of our Milky Way is 4.3 million times bigger than the sun.)
The supermassive black hole Sagittarius A*, imaged by the Event Horizon Telescope. [32] The complex astronomical radio source Sagittarius A appears to be located almost exactly at the Galactic Center and contains an intense compact radio source, Sagittarius A*, which coincides with a supermassive black hole at the center of the Milky Way.
The same scenario may play out with Sagittarius A*, the supermassive black hole at the center of the Milky Way, but astronomers aren’t sure how likely it is to occur, Ricci said.
