Scientists at Durham University have observed two million distant galaxies, quasars and stars for the first time as part of an effort to create a detailed map of the universe.
The study used robotics to take thousands of pictures of the night sky, with the aim of advancing our understanding of the universe and our galaxy, the Milky Way.
The team used the observed data taken from DESI to analyse extragalactic objects and how their light decomposed into different colours or wavelengths. These analyses could reveal the rate at which the universe is expanding, as well as the physical properties of the galaxies and quasars.
