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.

This image shows the location of the 43 quasars Lehner et al used to probe Andromeda’s gaseous halo. These quasars are scattered far behind the halo, allowing scientists to probe multiple regions. Looking through the immense halo at the quasars’ light, the team observed how this light is absorbed by the halo and how that absorption changes in different regions. By tracing the absorption of light coming from the background quasars, the astronomers are able to probe the halo’s material. Image credit: NASA / ESA / E. Wheatley, STScI.
