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 Webb observations mark the longest, most detailed look researchers have been able to make around the Milky Way’s central black hole, called Sagittarius A*, building on past evidence of its ...
Sagittarius A (Sgr A) is a complex radio source at the center of the Milky Way, which contains a supermassive black hole. It is located between Scorpius and Sagittarius , and is hidden from view at optical wavelengths by large clouds of cosmic dust in the spiral arms of the Milky Way.
One of the most studied stars is S2, a relatively bright star that also passes close by Sgr A*. As of 2020 [update] , S4714 is the current record holder of closest approach to Sagittarius A*, at about 12.6 astronomical units (1.88 × 10 9 km), almost as close as Saturn gets to the Sun, traveling at about 8% of the speed of light.
Three years after capturing the first image of a supermassive black hole in a galaxy 55 million light years away, astronomers have managed to "photograph" one closer to home.
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 ...
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]
