'''NGC 3079''' is a [[Astronomy:Barred spiral galaxy|barred spiral galaxy]] about 50 million light-years away, and located in the [[Astronomy:Constellation|constellation]] [[Astronomy:Ursa Major|Ursa Major]].  A prominent feature of this galaxy is the "bubble" forming in the very center (see picture below). The [[Astronomy:Supermassive black hole|supermassive black hole]] at the core has a mass of {{Val|2.4e6|2.4|1.2|ul=solar mass}}.<ref name=Graham2008>{{citation

==Center Bubble==
The bubble forming in the center of NGC 3079 is believed to be about 3000 light-years wide and to rise more than 3500 light-years above the disc of the galaxy.  It is speculated that the bubble is being formed by particles streaming at high speeds, which were in turn caused by a large burst of [[Astronomy:Star formation|star formation]].  This current bubble is thought to have been created about one million years ago, and computer modeling suggests that there is an ongoing cycle of forming bubbles, with a new bubble forming approximately every 10 million years.
