... Many of the brightest blue images are of a single, unusual, beaded, blue, ring-like galaxy which just happens to line-up behind a giant cluster of galaxies. Cluster galaxies here typically appear yellow and -- together with the cluster's dark matter -- act as a gravitational lens . A gravitational lens can create several images of background galaxies , analogous to the many points of light one would see while looking through a wine glass at a distant street light. ...
