An international team in which researchers from the Instituto de Astrofísica de Canarias (IAC) and the Universidad de La Laguna (ULL) are participating, observes how the magnetic waves which propagate through the solar atmosphere heat its outer layers. The results of this research are published today in the magazine Nature Physics.
