Why Is the Sun's Corona Hotter Than Its Surface?

💡 The Answer

• The Sun's corona reaches millions of degrees while the surface is only about 5,500°C, a puzzling temperature inversion.
• Scientists believe magnetic reconnection releases energy as nanoflares, heating the corona to extreme temperatures.
• Plasma waves traveling along magnetic fields may also transfer energy from the Sun's interior to the corona.
• This mystery remains one of the biggest unsolved problems in solar physics and space weather research.
