NGC 3079 is a barred spiral galaxy about 50 million light-years away, and located in the constellation Ursa Major. A prominent feature of this galaxy is the "bubble" forming in the very center (see picture below). The supermassive black hole at the core has a mass of 2.4+2.4
−1.2×106 M☉.[3]
Two supernovae have been observed in NGC 3079: SN 2001ci (type Ic, mag. 18.3),[4] and SN 2013ee (type II, mag. 15.5).[5]
