Abell 2218 is a cluster of galaxies about 2 billion light-years away in the constellation Draco. Acting as a powerful lens, it magnifies and distorts all galaxies lying behind the cluster core into long arcs. There are two arcs, z = 1.03 corresponds approx. to 6 billion light-years, z = 0.7 corresponds approx to 6.5 billion light-years.
