Dark Matter Map in Galaxy Cluster Abell 1689 – Astronomy Picture of the Week
This image represents the inner region of galaxy cluster Abell 1689 and the distribution of dark matter around it. Abell 1689 is an immense cluster of galaxies located 2.2 billion light-years away. Dark matter cannot be photographed, but its presence can be inferred by observing the light from background galaxies…
Astronomy Picture of the Week – Hubble Finds Ring of Dark Matter
This composite image of a ghostly ring of dark matter in the galaxy cluster Cl 0024+17 was taken by the NASA/ESA Hubble Space Telescope in November 2004. A false color map is superimposed on a Hubble image of the cluster in order to make the cluster's dark matter distribution more evident.
Astronomy Picture of the Week – Pandora’s Cluster
