The Most Shocking Discovery in Astrophysics Is 25 Years Old

The Dark Energy Spectroscopic Instrument (DESI) will spend five years creating a 3-D map of the universe that will help reveal the nature of the dark energy driving cosmic expansion. The project's first six months of data show slivers of the universe that represent just 1 percent of the survey's ultimate volume of space. The colors represent different types of galaxies, including nearby bright galaxies in yellow, luminous red galaxies in magenta and galaxies with supermassive black holes in turquoise.

Experiment to Capture Universe’s Earliest Moments Reaches Funding Milestone

For CMB-S4, a new set of telescopes will be built to map the light from the aftermath of the Big Bang in greater detail than ever before. The instruments will be installed at the South Pole (shown here) and in Chile. Geoff Chen

New Map of Space Precisely Measures Nearly 400,000 Nearby Galaxies

NGC 520 is one of the largest and brightest galaxies in the Siena Galaxy Atlas. It is made of two disk galaxies that will eventually merge together to form one massive system. NSF/AURA/NOIRLab/T.A. Rector (University of Alaska Anchorage/NSF’s NOIRLab) & M. Zamani (NSF’s NOIRLab)
