Story summary

Scientists using the Daniel K. Inouye Solar Telescope in Hawaii made the first observation of twisting magnetic waves called Alfvén waves, and the findings were published in Nature Astronomy.
The waves had been theorized since 1942.
The findings indicate Alfvén waves carry substantial energy, potentially accounting for half the energy needed to heat the corona.
The study could improve predictions of solar wind and solar dynamics.
