Abell 3827: Cannibal Cluster Gravitational Lens
This Hubble image of galaxy cluster Abell 3827 shows what appears to be a curved galaxy with three centers. This is actually three images of the same background galaxy. The light from the single blue galaxy takes multiple paths through the complex gravity of the cluster. This phenomenon is called gravitational lensing.
