Comments of unusual morphologies; e.g., E3, but with dust ring small bright nucleus brightest member of a remarkable group known as the Sombrero Galaxy contains some dust and hints of recent star formation seems to be a population of stars richer in heavy elements average size for spiral galaxies in the universe one of the brightest member galaxies interacting with the Whirlpool Galaxy considerably less luminous and massive than the greatest ellipticals in this cluster undergoing an extremely high rate of star forming activity absorbing dust in front of the nucleus that results in a smudged appearance brightest member of the M74 Group home to supermassive black holes of between 10 and 100 million solar masses e ncircled by thick dust lanes comprising the

spiral structure of the galaxy visible in Earth's Southern Hemisphere skies located in the constellation Ursa one of the brighter member galaxies one of the most remote objects in the Messier catalogue also known as Virgo A or the Smoking Gun
