. An irregular ring of radiation can be seen around the distant galaxy in the center of this 2.2-micron CCD photograph, made with the 10-meter Keck telescope on Hawaii. The lensing galaxy is associated with radio source 3C 220.3. The radiation of the ring originates from an extremely distant galaxy-in-formation and is a result of the gravitational-lens effect. Just below the lensing galaxy a neighboring galaxy can be seen, which also contributes to the lensing effects. ESA and the W. M. Keck Observatory
