Question

WHY DEOS STARS GLITTERS

Answer 1

Stars twinkle because of turbulence in the atmosphere of the Earth. As the atmosphere churns, the light from the star is refracted in different directions. This causes the star's image to change slightly in brightness and position, hence "twinkle."

Answer 2

Light of stars passes through many layers of atmosphere from denser to rarer.Due to this atmospheric refraction stars looks to be twinkling.
