 Astronomer Timothy Hamilton, using Hubble Space Telescope, discovered these unusual objects now named after him. The objects are the stretched images of a gravitationally-lensed distant galaxy located more than 11 billion light-years away. One appears to be a mirror image. In this case, a precise alignment between the background galaxy and a foreground galaxy clustered 7 billion light-years away produced twin magnified copies of the same image of the remote galaxy. This rare phenomenon occurs because the background galaxy straddles a ripple of dark matter in the foreground galaxy. As the far away galaxy light passes through the cluster along this ripple, two mirror images are produced. Along with a third image, they can be seen off to the side.
