Why Is the Sun's Corona So Hot?

The video explores the solar corona, the outermost layer of the sun's atmosphere, which is significantly hotter than the sun's surface. It discusses two main hypotheses for this phenomenon: wave heating and magnetic reconnection. Wave heating involves energy from turbulence on the sun's surface traveling to the corona, while magnetic reconnection involves energy release from magnetic domains in the sun's plasma. To gather more data, NASA plans to launch the Parker Solar Probe to study the corona's heating mechanisms. The probe will fly closer to the sun than any previous mission, aiming to solve the mystery of the corona's extreme temperatures.
