The twinkling of stars in our night sky is due to Earth's atmosphere. Stars twinkle as the light from the stars gets retracted by the movement of the air the atmosphere. This refraction causes slight changes in the brightness and position in the star'simage , causing the twinkling of stars .
Answer:
Stars do not really twinkle, they just appear to twinkle when seen from the surface of Earth. The stars twinkle in the night sky because of the effects of our atmosphere. When starlight enters our atmosphere it is affected by winds in the atmosphere and by areas with different temperatures and densities.
Twinkling of stars is due to atmospheric refraction of star light. The star light after entering the earth's atmosphere undergoes refraction in a continuous manner before it reaches the Earth. The atmospheric refraction is due to change in the refractive index at different level in atmosphere.
