Corona
Corona is the outermost layer of the Sun's atmosphere, which is visible during a total solar eclipse. It is a plasma of ionized gas that extends millions of kilometers into space and has a temperature of over a million degrees Celsius. The corona is constantly changing and is influenced by the Sun's magnetic field. It is also the source of the solar wind, a stream of charged particles that flows outwards from the Sun and affects the Earth's magnetic field and atmosphere.
