New 3-D Map of Massive Galaxies and Distant Black Holes Offers Clues to Dark Matter and Dark Energy

[The Sloan Digital Sky Survey III (SDSS-III) has released the largest-ever three-dimensional map of massive galaxies and distant black holes, which will help astronomers explain the mysterious [dark matter] and [dark energy] that scientists know makes up 96 percent of the Universe.
Early last year, the SDSS-III released the largest-ever image of the sky. With the new release of data, SDSS-III has begun to expand this image into a full three-dimensional map. Data Release 9 (DR9), posted online last week, makes available the first third of the galaxy map that this six-year project will create]. – SDSS-III

[A video 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]. – SDSS-III
