galactic center

(galactic core, center of the Milky Way)
(region at the middle of the Milky Way)

The galactic center (or galactic core) is the middle of the Milky Way, around 8 kpc distant in the direction of Sagittarius. Dust obscures observation, but a supermassive black hole (SMBH) known as Sagittarius A* has been discerned. Surrounding the SMBH is a compact stellar nucleus, and around that is the galactic bulge, a dense grouping of stars, and around that is a bar, some kpc in length.
