CMB-S4 – Ground Based CMB Cosmology Program

CMB-S4 is the next-generation ground-based cosmic microwave background experiment.

With 21 telescopes at the South Pole and in the Chilean Atacama desert surveying the sky with over 500,000 cryogenically-cooled superconducting detectors for 7 years, CMB-S4 will deliver transformative discoveries in fundamental physics, cosmology, astrophysics, and astronomy.

CMB-S4 is supported by the Department of Energy Office of Science and the National Science Foundation.
