Hubble Pinpoints Farthest Protocluster of Galaxies Ever Seen

NASA, ESA, M. Trenti (University of Colorado, Boulder, and University of Cambridge, UK), L. Bradley (STScI), and the BoRG team

This image, released on Jan. 10, 2012, shows the farthest primitive galaxy cluster yet known in a image of the BoRG 58 region.

Winter Dark Matter Alternative Color

Van Waerbeke, Heymans, and CFHTLens collaboration

The observations show that dark matter in the Universe is distributed as a network of gigantic dense (light) and empty (dark) regions, where the largest dense regions are about the size of several Earth moons on the sky.

Dark Matter Densest Regions

Van Waerbeke, Heymans, and CFHTLens collaboration

The densest regions of the dark matter cosmic web host massive clusters of galaxies.

This image, released on Jan. 10, 2012, shows a close-up of the farthest primitive galaxy cluster yet known in a image of the BoRG 58 region.

Dark Matter Surveyed by Canada-France-Hawaii Telescope, Winter

Van Waerbeke, Heymans, and CFHTLens collaboration

The observations show that dark matter in the Universe is distributed as a network of gigantic dense (white) and empty (dark) regions, where the largest white regions are about the size of several Earth moons on the sky.

El Gordo — A "Fat" Distant Galaxy Cluster

ESO/SOAR/NASA

This picture of the galaxy cluster ACT-CL J0102-4915 combines images taken with ESO’s Very Large Telescope with images from the SOAR Telescope and X-ray observations from NASA’s Chandra X-ray Observatory. The X-ray image shows the hot gas in the cluster and is shown in blue. This newly discovered galaxy cluster has been nicknamed El Gordo — the "big" or "fat one" in Spanish. It consists of two separate galaxy subclusters colliding at several million kilometres per hour, and is so far away that its light has travelled for seven billion years to reach the Earth.
