An artist’s illustration depicts the supermassive black hole at the center of the Milky Way galaxy, known as Sagittarius A*. It’s surrounded by a swirling accretion disk of hot gas and dust.
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 hole of about 4 million solar masses, which is called Sagittarius A*, [3] [4] [5] a compact radio source which is almost exactly at the galactic rotational center.
In the television show Community, Pierce Hawthorne mentions that in his opinion, Sagittarius A* is the only black hole worth studying. In the final arc of the Sailor Moon manga series, "Sagittarius Zero Star" is the location of the Galaxy Cauldron, a fictional artifact that serves as the birthplace of all life in the Milky Way.

The structure of the magnetic field emanating from the edge of the black hole called Sagittarius A*, or Sgr A*, closely resembles one surrounding the only other black hole ever imaged, a larger ...
A new image of the black hole that lies at the center of our Milky Way galaxy shows that it is surrounded by a strong, twisting magnetic field.
Scientists have revealed an astonishing new image of the black hole in the middle of our galaxy. The object – known as Sagittarius A* – is shown in polarised light for the first time, in a ...
Measurements with the Hubble Space Telescope in 2006 suggest the Magellanic Clouds may be moving too fast to be orbiting the Milky Way. [3] Of the galaxies confirmed to be in orbit, the largest is the Sagittarius Dwarf Spheroidal Galaxy, which has a diameter of 2.6 kiloparsecs (8,500 ly) [4] or roughly a twentieth that of the Milky Way.
