Solar Mystery Deepens: How the Sun's Atmosphere Gets Hotter Than Its Surface

For more than eighty years, the Sun has kept a quiet secret: its outer atmosphere burns hundreds of times hotter than its own visible surface, a paradox that defies casual intuition while obeying deeper physical laws. The energy does not conduct upward like warmth from a hearth — it travels through magnetic fields, arriving in the corona as something other than ordinary heat. Two candidate mechanisms, rippling Alfvén waves and Eugene Parker's theorized nanoflares, have long competed to explain where that energy finally releases, and now NASA's Parker Solar Probe, having passed closer to the Su
