Atmospheric Refraction....

Refraction which takes place from Earth's atmosphere is called atmospheric refraction.

Different layers of Earth's atmosphere have different densities. Hence when light passes from it , it gets refracted .

Application of atmospheric refraction.

Twinkling of stars.....

In fact stars does not twinkle , they appear twinkling bcz of atmospheric refraction . When the star light passes from Earth's atmosphere it gets refracted and the star twinkles.

Planet does not twinkle bcz they don't have the light of their own . They are closer to the Earth , they are extending source of light and they nullify twinkling effect.
