80 Years in the Making: Scientists Finally Capture the Sun’s Mysterious Magnetic Waves
Scientists have finally discovered twisting magnetic waves in the Sun. An eight-decade hunt that began in the 1940s has now been brought to a successful conclusion. These waves are known as torsional Alfvén waves. Using the powerful Daniel K. Inouye Solar Telescope, researchers were able to record the first direct evidence of these modest, continuous waves. These waves may be responsible for heating the outer atmosphere of the Sun to millions of degrees.
R. J. Morton, Y. Gao, E. Tajfirouze, H. Tian, T. Van Doorsselaere and T. A. Schad published their discovery under the title “Evidence for small-scale torsional Alfvén waves in the solar corona” in October 2025.
ENTECH STEM Magazine has included this research in its list of the Top 10 Astronomy Discoveries of 2025
