A slide through 3-D map of galaxies from the completed SDSS survey (left) and from the first few months of the DESI survey (right). The earth is at the center, with the furthest galaxies plotted at distances of 10 billion light years. These galaxies are selected from the 2-Dmap constructed by the imaging surveys. Each point represents one galaxy.
