Summary

The Dark Energy Spectroscopic Instrument ( DESI ) has successfully completed the largest high-resolution 3D map of the universe ever made, a major milestone in understanding the force driving cosmic expansion. The milestone was reached when DESI's 5,000 fiber-optic sensors captured their final scheduled observations, targeting a region of sky near the Little Dipper. Many institutions globally are involved in the project, including the University of Portsmouth, University College London and Durham University along with Berkeley Lab and the Science and Technology Facilities Council.
