What are the names of the three layers of the suns atmosphere?

The three layers of the Sun's atmosphere are the photosphere, chromosphere, and corona. The photosphere is the visible surface of the Sun, while the chromosphere lies above it and is characterized by a reddish glow during eclipses. The corona is the outermost layer, extending millions of kilometers into space and visible during a total solar eclipse as a halo of plasma. Each layer plays a crucial role in solar phenomena and the Sun's overall behavior.
