During a solar eclipse, which layers of the Sun become visible from Earth?

During a solar eclipse, the chromosphere and the corona become visible from Earth. A solar eclipse occurs when the Moon passes between the Earth and the Sun, temporarily blocking out the Sun's light. When the Sun is obscured during a total solar eclipse, the outer layers of the Sun that are usually hidden by the bright light of the photosphere become visible.

The chromosphere appears as a reddish glow surrounding the Sun, which can be seen just before and after the totality of the eclipse. The corona, which is the Sun's outer atmosphere, is visible as a faint halo around the Sun and is characterized by its wispy appearance. This phenomenon allows astronomers to study these layers during total solar eclipses, providing valuable insights into solar dynamics and behavior. The photosphere, while important, is the layer of the Sun that is typically visible under normal circumstances and is obscured during an eclipse, making it not one of the visible layers during this event.
