Sgr B2

(Sagittarius B2)
(GMC near the galactic center)

Sgr B2 (Sagittarius B2) is a giant molecular cloud (GMC) about 120 pc from Sag A*, the Milky Way's central supermassive black hole (SMBH). Sgr B2 is about 45 pc across, very dense for such a cloud, and hosts significant star formation. X-rays from it are interpreted as a response to a past outburst of gamma rays from Sag A*.
