Description

Abell 2151 (AKA The Hercules Galaxy Cluster) is another plunge into the universe of small. distant galaxies. I've read that the average distance to the galaxies in the cluster is 500 million light years. It's hard to imagine that something so far away can show up as something more than a dot (or even a dot). I think that helps give some scale to just how big galaxies are!
