The corona is an envelope of ionized gases that extends out past the sun.
The corona is the third layer of the Sun. This layer takes the out most portion of the Sun's atmosphere. It is consisted of ionized gases that normally extend around one million kilometers from the Sun's surface.
Because of the shadow, it chills the place down, it's not facing the Sun, matter of fact its the farthest from the Sun, because the Earth is tilted and deserts tend to be on equator where the Earth gets the most sunlight.
