This is the first Dark Energy Survey map to trace the detailed distribution of dark matter across a large area of sky. The color scale represents the density of mass: Yellow and red are regions with more dense matter; green and blue are regions with less dense matter. Superimposed on this map are clusters of galaxies shown by the gray dots. The dark matter map conforms to the current picture of mass distribution in the universe where large filaments of matter align with galaxies and clusters of galaxies.
