M61

Located in the constellation of Virgo, amidst the cluster of galaxies know as the Virgo cluster, is a spiral galaxy known as M61. This is one of the larger galaxies in the cluster, measuring in at about 100,000 light years in diameter.

M61 = NGC4303 ( 12h 21.9m +4°28´, 9.7 mag. ) This spiral galaxy in Virgo was discovered by Oriani in May 1779 and Messier observed it on May 11 the same year. At 100,000 ly across, this is one of larger galaxies in Virgo Cluster.

M61: armed spiral seen face-on, very bright. This is one of the largest galaxies associated with the Virgo Cluster, and may have a mass of fifty billion Suns. Three supernovae have occurred in M61, the last in 1964.

M61 Vulcan The M61 Vulcan is a 20 mm hydraulically or pneumatically driven, six-barrel ed, air-cooled, electrically fired Gatling gun with an extremely high rate of fire.... cannon for close range dogfighting.

4, it is well over three times brighter than M61. Larger in apparent diameter as well, M49 spans 9 arcminutes across, nearly twice as wide across as M61.

The Virgo cluster is a massive cluster of over 100 galaxies (including M61, M87, M90, and M100) and a lot of very hot, X-ray emitting gas. This cluster is located mostly within the constellation Virgo.
