The universe has a hidden structure, and a University of Virginia professor is mapping it in 3D, using 46 million galaxies and quasars and 19 million stars. Satya Gontcho A Gontcho, an assistant professor in the Department of Astronomy, is part of a team using the Lawrence Berkeley National Laboratory-led, Arizona-based Dark Energy Spectroscopic Instrument to conduct one of the most extensive surveys of the cosmos ever. DESI has built the largest 3D map of the universe ever created by humanity to study dark energy, one of the biggest mysteries in physics.
