This video is a fly-through of the SDSS-III galaxies mapped in Data Release 9. Each galaxy in the animation is placed at the location mapped by SDSS and is represented by the zoomed-in template image that matches the actual shape of the galaxy.
Galaxies are concentrated into clusters and filaments with voids in between. The SDSS-III is exploring this structure to determine the nature of dark energy and the distribution of dark matter in the Universe.
