Alfvén Waves Unlocked: The Force Heating the Solar Corona

Did you know that the outer atmosphere of the Sun is hundreds of times hotter than its surface, defying basic logic about heat sources? This mystery has puzzled researchers for decades because temperatures jump from 6 000 degrees Celsius at the surface to over a million degrees in the corona. You might expect the heat to drop as you move away from the core but the Sun works differently. Recent data now points toward magnetic vibrations as the primary delivery system for this energy - these vibrations, known as Alfvén waves, travel along magnetic field lines like waves moving down a plucked guitar string. Scientists are finding that these waves carry enough power to keep the corona glowing and hot.
