Virgo cluster still being formed
The Virgo Galaxy Cluster is Still Being Formed
Quote:

At a distance of only 50 million light-years away, the Virgo Cluster is the nearest galaxy cluster to us. It's a giant structure consisting of hundreds of galaxies, both large and small, spiral and elliptical; 16 objects in this cluster are members of the famous Messier list of space objects. Astronomers have located a large number of planetary nebula floating in the "intercluster" space between galaxies, and theorize that they must be a fraction of the free floating stars and other objects which swarm around the cluster. By measuring the path of these objects, astronomers have been able to track how the Virgo Cluster is still in the process of formation.
