Large-scale structure in the universe in the northern and southern galactic hemispheres. Each of the 9,325 points in this image represents a galaxy. The Earth lies at the center; unmapped regions to the top and bottom are inaccessible because the plane of the Milky Way obscures them. Note the large-scale patterns in both hemispheres, like the Great Wall stretching across the northern hemisphere.
