Parts of the Sun

The Sun is a multiple layered entity. Deep inside the core matter is packed so dense as to cause nuclear fusion to take place. The energy produced from the fusion radiates outward until eventually it reaches a point where the density of the matter is no longer enough to contain it. Photons of energy emerge from the photosphere producing the ball of light we see in the sky. When the photosphere is completely covered as during a total solar eclipse we can see more layers. Closest to the photosphere is the chromosphere. It is red/pink in color and best seen just after second contact and before third contact. Outside the chromosphere is the corona. The corona extends out past the orbit of the Earth dimming quickly. When observed during an eclipse one can see the corona extending out several degrees from the edge of the moon.
