Galaxies in a cosmic house of mirrors

Webb's Picture of the Month shows galaxy cluster MACS J0454.1-0300, whose gravity warps and multiplies the galaxies behind it. The orange galaxies concentrated on one side are much farther away than the cluster, which is itself seen as it was when the universe was about 8 billion years old. No backyard telescope can show this gravitational lensing, but it explains why Webb keeps pointing at galaxy clusters.
