Zooming in on the remote cluster CL J1449+0856

This sequence starts with a view of the constellation of Boötes (The Herdsman) and the bright star Arcturus. As we zoom in we can see many faint stars in the Milky Way and then, as we go even deeper, huge numbers of remote galaxies become visible. The final detailed view shows an image of the most remote mature galaxy cluster yet found — appearing as a scattering of faint red objects. This image was created from many long exposures in both optical and near-infrared light using exposures from both ESO’s Very Large Telescope and the Subaru telescope on Hawaii.
