First direct observation of elusive waves reveals energy channels in solar atmosphere

For the first time, torsional Alfvén waves have been directly observed in the solar corona by a team of researchers from the University of Oslo and the University of Warwick. The discovery sheds light on the origin of magnetic waves and their role in the heating of the sun’s corona.
