A team of scientists at the University of Virginia is using a telescope in Arizona to study cosmic structure and the result is the largest 3D map of the Universe ever created. The Dark Energy Spectroscopic Instrument (DESI) at Kitt Peak National Observatory is their tool, and the ultimate goal is to get a handle on the mystery of dark energy by charting the positions of galaxies.
