Using new numerical simulations, scientists from the CEA, the CNRS and the University Paris-Diderot can explain why the Sun's magnetic field reverses every eleven years. To be published in the July 14, 2017 issue of Science, the discovery of a scaling law for determining the magnetic cycle period of a star is pioneering and helps us comprehend violent space weather phenomena.
