Galaxy cluster Abell 2218 acts as a powerful lens, magnifying all galaxies lying behind the cluster core. The lensed galaxies are all stretched along the cluster's center and some of them are multiply imaged. ... The color of the lensed galaxies is a function of their distances and types. The orange arc is an elliptical galaxy at moderate redshift (z = 0.7). The blue arcs are star-forming galaxies at intermediate redshift (z = 1-2.5). ...
