Tracing Diffuse Starlight in Galaxy Cluster Abell S1063

Hubble's powerful sensitivity and resolution captures a soft blue haze, called intracluster light, among innumerable galaxies in the Abell S1063 cluster. The stars producing this glow have been thrown out from their galaxies. These stars now live solitary lives, no longer part of a galaxy but aligning themselves with the gravity of the overall cluster. Astronomers have found that intracluster light's association with a map of mass distribution in the cluster's overall gravitational field makes it a good indicator of how invisible dark matter is distributed in the cluster.
