From Nature, Sept. 5, 2017: Maps of the cosmic microwave background have become iconic representations of the early universe. But when the Dark Energy Survey collaboration unveiled the analysis of their first year of data last month, many felt that a new era had started.

The 50-foot-wide superconducting electromagnet at the center of the experiment saw its first beam of muon particles from Fermilab’s accelerators, kicking off a three-year effort to measure just what happens to those particles when placed in a stunningly precise magnetic field. The answer could rewrite scientists’ picture of the universe and how it works.
