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.

$This is one slice through the map of the large-scale structure of the Universe from the Baryon Oscillation Spectroscopic Survey. Each dot in this picture indicates the position of a galaxy 6 billion years into the past. The image covers about 1/20th of the sky, a slice of the Universe 6 billion light-years wide, 4.5 billion light-years high, and 500 million light-years thick. Color indicates distance from Earth, ranging from yellow on the near side of the slice to purple on the far side. Galaxies are highly clustered, revealing superclusters and voids whose presence is seeded in the first fraction of a second after the Big Bang. This image contains 48,741 galaxies, about 3% of the full survey dataset. Grey patches are small regions without survey data. Image credit: Daniel Eisenstein / SDSS-III Collaboration.$
