The recent achievement of astronomers using the Dark Energy Spectroscopic Instrument (DESI) on NSF’s Nicholas U. Mayall 4-m telescope has revolutionized our understanding of the universe. This groundbreaking project has produced the largest high-resolution 3D map of the universe, tracing the positions of over 47 million galaxies and quasars. The sheer scale and scope of this endeavor are remarkable, with DESI far surpassing its original goals. By comparing how galaxies clustered in the past with their current distribution, astronomers can trace the influence of dark energy over 11 billion years of cosmic history. This ambitious project, managed by Berkeley Lab (Read more…)
