NGC 4571
Galaxy in the constellation Coma Berenices
From Wikipedia, the free encyclopedia
NGC 4571 is a spiral galaxy located in the constellation of Coma Berenices. It was discovered by German-British astronomer William Herschel on 14 January 1787.[2] It was also observed by German astronomer Friedrich Schwassmann on 23 November 1900, causing it to be listed in the Index Catalogue as IC 3588.[2] John Dreyer thought this galaxy might be the "lost" Messier 91, but in 1969, amateur astronomer William C. Williams realized that M91 was actually NGC 4548.[3]

Physical properties
The finding of Cepheids by the Canada France Hawaii Telescope in 1994 has established that this galaxy is a member of the Virgo Cluster.[3]
Despite being classified as a late-type galaxy, NGC 4571 has features more typical of spiral galaxies of earlier Hubble type such as a high color index, both low star formation rate and H-Alpha brightness, and relatively little neutral hydrogen,[4] suggesting it may have lost most of its gas due to interactions with Virgo's intragalactic medium and/or past interactions with other galaxies of the cluster.[5][6][7]
The low-surface brightness galaxy Malin 1 is located close to this object.[8] It is totally unrelated, however as it lies at a much higher distance.
