T his image from NASA's Hubble Space Telescope shows hundreds of galaxies in an area of the sky as small as President Roosevelt's eye on a dime held at arm's length. The brightest galaxy in the field, called NGC 4881, lies in the outskirts of a really large cluster of galaxies called the Coma Cluster. Galaxy Clusters Galaxies, themselves giant assemblies of stars, dust and gas, are collected in clusters containing dozens to thousands of members. Our Milky Way Galaxy is a member of a small cluster of 40 galaxies. The Coma Cluster contains 1,000 large and thousands of smaller galaxies packed closely together.
