The findings come from Hubble's survey of more than 11,000 globular clusters in 100 galaxies of various sizes and shapes. All those galaxies are contained in the Virgo Cluster, an assemblage of about 2,000 galaxies that is a mere 54 million light-years from our own Milky Way. From that distance, Hubble was able to pick out the star clusters even in dim dwarf galaxies. Video is of average quality, there is no talking or music in this video. This is a very short video, appropriate for middle school or high school students looking at Virgo Cluster.
