NGC 4450 imaged by the Hubble Space Telescope

NGC 4450 is a spiral galaxy in the constellation Coma Berenices.


NGC 4450 is a member of the Virgo Cluster that, like Messier 90, shows smooth, nearly featureless spiral arms,[3] with few star formation regions[4] and little neutral hydrogen compared to other similar spiral galaxies,[5] something that justifies its classification as an anemic galaxy.[4]

Measurements with the help of the Hubble Space Telescope show the center of this galaxy has a supermassive black hole.[6]
