This Hubble image shows the inner region of Abell 1689, an immense cluster of galaxies located 2.2 billion light-years away. The cluster’s gravitational field is warping light from background galaxies, causing them to appear as arcs. Dark matter in Abell 1689, which represents about 80% of its mass, is mapped by plotting these arcs. Image credit: NASA / ESA / JPL-Caltech / Yale / CNRS.
