The Galactic Center & Sagittarius A*: Advanced Connections

At the dynamical center of the Milky Way lies Sagittarius A*, a compact radio source associated with a supermassive black hole of roughly four million solar masses. The Galactic center provides the nearest laboratory for testing supermassive black-hole gravity, stellar dynamics, accretion, and the relation between black holes and galactic nuclei.

Stars orbit the central mass under strong gravity, while gas falling inward can heat and radiate before reaching the black hole.
