Mystery of coronal heating problem: Magnetically driven resonance helps heat sun's atmosphere

Solar physicists have captured the first direct observational signatures of resonant absorption, thought to play an important role in solving the 'coronal heating problem' which has defied explanation for over 70 years. An international research team combined high resolution observations from JAXA's Hinode and NASA's IRIS mission, together with state-of-the-art numerical simulations and modeling from NAOJ's ATERUI supercomputer. In the combined data, they were able to detect and identify the observational signatures of resonant absorption.
