Sagittarius A*, abbreviated Sgr A* ( / ˈsædʒ ˈeɪ stɑːr / 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 ...
SIMBAD. data. 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.
The Galactic Center, as seen by one of the 2MASS infrared telescopes, is located in the bright upper left portion of the image. Marked location of the Galactic Center. 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 ...
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 ...
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. Supermassive black hole in Milky Way, at 'heart ...
The Milky Way [c] is the galaxy that includes the Solar System, with the name describing the galaxy's appearance from Earth: a hazy band of light seen in the night sky formed from stars that cannot be individually distinguished by the naked eye.
This is considered one of the highest masses ever recorded for such an object; higher than the mass of all the stars in the Milky Way galaxy combined, which is 64 billion solar masses, and 15,300 times more massive than Sagittarius A*, the Milky Way's central black hole. With such high mass, TON 618 may fall into a proposed new classification ...
