The photo for the week of February 10, 2008 is of Abell 2218: A Galaxy Cluster Lens. This image was captured by the Hubble Space Telescope viewing the cluster Abell 2218. The gravity in this cluster bends and focuses light from the surrounding galaxies that are located directly behind it. The cluster is located some 3 billion light-years in the in constellation known as Draco. The cluster is still quite young, distorting the galaxies and stars into long faint arcs.
