Galaxy clusters

Galaxy clusters are bassiclly big clumps of galaxies. Each Galaxy cluster has 1,000 galaxies to 1,000,000 (Anything above 1,000,000 is a supercluster) Our galaxy is in the local galactic group galaxy cluster and the virgo supercluster. With the Hubble telescope, sciencetists made a picture of the whole known universe which contained all the galaxy clusters and superclusters. If you look at it, it's like a sponge.
