Drag green handle to reveal images
A slice through the 3D map of galaxies from the completed Sloan Digital Sky Survey (right) and from the first few months of the Dark Energy Spectroscopic Instrument (DESI; left). Earth is at the center, with the furthest galaxies plotted at distances of 10 billion light-years. Each point represents one galaxy. This version of the DESI map shows a subset of 400,000 of the 35 million galaxies that will be in the final map.
