Messier 101: Pinwheel Galaxy It has the designation NGC 4501 in the New General Catalogue. Different LFs for Different Environments   Messier 88 has a very regular spiral arm structure and is classified as type Sbc spiral galaxy, which means that its spiral arms are between medium-wound (Sb) and loosely-wound (Sc). As a result of their motion through the densely populated Virgo Cluster, M88 and many other cluster members are experiencing ram pressure stripping, a process that strips a galaxy’s outer region of neutral hydrogen.

It has a luminosity 2,254 times that of the Sun. Because of its moderate brightness, Zavijava should be easily visible from locations with dark skyes, while it can be barely visible, or not visible at all, from skyes affected by light pollution.
