Unraveling the Enigma: Explaining the Sun's Surprisingly Hot Atmosphere

Mysterious high-frequency magnetic waves detected by the Solar Orbiter spacecraft may explain why the sun's upper atmosphere, known as the corona, is 200 times hotter than its surface. This phenomenon, known as the coronal heating problem, has puzzled scientists for decades. Observations of small and rapid oscillations in magnetic structures in the corona suggest that magnetic waves could be responsible for heating the corona. Further research and observations will be conducted to confirm this link and understand the role of high-frequency magnetic waves in coronal heating.
