The bright light at the centre of this image is galaxy cluster Abell S1063, which lies 4.5 billion light years from Earth. Photographed by the James Webb Space Telescope, this cluster is so massive that light from galaxies behind bends around it, creating the surrounding warped red arcs. This gravitational lensing lets the cluster act as a magnifying glass through which we can peer into the early days of the universe.
