There are a number of stars in close orbit around Sagittarius A*, which are collectively known as "S stars". [73] These stars are observed primarily in K band infrared wavelengths, as interstellar dust drastically limits visibility in visible wavelengths.
The Sagittarius A* cluster is the cluster of stars in close orbit around Sagittarius A*, the supermassive black hole at the center of the Milky Way (in the Galactic Center).
12 Μαΐ 2022 · Sagittarius A*, often abbreviated to Sgr A* and pronounced "Sagittarius A star", is a supermassive black hole located at the center of our spiral galaxy, the Milky Way.
29 Αυγ 2013 · The center of the Milky Way galaxy, with the supermassive black hole Sagittarius A* (Sgr A*), located in the middle, is revealed in these images. As described in our press release, astronomers have used NASA’s Chandra X-ray Observatory to take a major step in understanding why material around Sgr A* is extraordinarily faint in X-rays.
A Story Of Black Holes: Sagittarius A*. Identifying our galaxy’s supermassive black hole by tracking stars’ orbits. A black hole is a region of space packed with so much mass that its own gravity prevents anything from escaping—even a ray of light.
Sagittarius A*, supermassive black hole at the center of the Milky Way Galaxy, located in the constellation Sagittarius and having a mass equivalent to four million Suns. The event horizon of the black hole has a radius of 12 million kilometers (seven million miles).
25 Μαΐ 2022 · The black hole’s accretion disk is supplied by matter flowing from stars that orbit Sagittarius A* in a disk about 0.3 parsecs (one light year) across, he says.
