Webb Focuses on Behemoth Galaxy Cluster: Abell S1063

May 27, 2025 by Enrico de Lazaro

Astronomers using the NASA/ESA/CSA James Webb Space Telescope have captured a remarkable new image of the galaxy cluster Abell S1063. This Webb image shows...

This Hubble image shows the massive galaxy cluster MACSJ 1206. Embedded within the cluster are the distorted images of distant background galaxies, seen as arcs and smeared features. These distortions are caused by the dark matter in the cluster, whose gravity bends and magnifies the light from faraway galaxies, an effect called gravitational lensing. This phenomenon allows astronomers to study remote galaxies that would otherwise be too faint to see. Overlaid on the image are small-scale concentrations of dark matter, represented in this artist’s impression in blue. Dark matter is the invisible glue that keeps stars bound together inside a galaxy and makes up the bulk of the matter in the Universe. These blue halos reflect how the galaxy cluster’s dark matter is distributed, revealed by new results from Hubble. Image credit: NASA / ESA / Hubble / G. Caminha, University of Groningen / M.
