About this Image
NGC 4216, located in the center of this image is an edge-on barred spiral galaxy not far from the center of the Virgo Cluster of galaxies.
Due to the internal motions of galaxies inside the Virgo Cluster it's redshift cannot be used to determine it's distance.
The entire group of galaxies is moving away from us, but NGC 4216 is moving towards us with respect to other group members.
