This image made by the NASA/ESA Hubble Space Telescope shows Abell 1703 which is composed of over one hundred different galaxies whose collective mass acts as a gravitational lens. The massive galaxy cluster in the foreground (yellow mostly elliptical galaxies scattered across the image) bends the light rays of galaxies behind it in a way that can stretch their images into multiple arcs. Abell 1703 is located at 3 billion light-years from the Earth. (Photo by NASA/ESA, and Johan Richard (Caltech, USA) via AP Photo)
