Multiple images, ghostly rings of light, luminous cross-shaped apparitions, and distorted galactic arcs all betray the powerful bending of light during macrolensing events--alignments that occur over millions of years as galaxies and galaxy clusters pass in front of more distant galaxies and quasars.
In addition to the simple cases of double-imaged quasars, macrolensing achieves some very striking visual effects.
