Nuclear Bulge
The spherical concentration of stars at the center of the Milky Way, roughly ten thousand light-years in diameter, composed mainly of old stars with randomly oriented orbits.
Timeline (last 90 days)
The Galactic Center usually refers to the innermost region of the Milky Way spanning tens of thousands of light-years, containing three key layers: the nuclear bulge, the nuclear star cluster, and Sagittarius A*.
The nuclear bulge is the spherical concentration of stars at the center of the Milky Way, about ten thousand light-years in diameter, composed mainly of old stars with randomly oriented orbits.
Sagittarius A* accounts for only about one ten-thousandth of the mass of the surrounding nuclear bulge, and its accretion rate is extremely low, making its power far inferior to that of active galactic nuclei.
