Due to atmospheric refraction of light.

Vedclass · Answer

(B) Stars emit their own light and they appear to twinkle due to the atmospheric refraction of light.Stars are located at a very large distance from the Earth,so they act as point sources of light.As the light from a star enters the Earth's atmosphere,it undergoes continuous refraction due to the changing density of air at different altitudes.This varying refraction causes the apparent position and brightness of the star to fluctuate.When more light reaches our eyes,the star appears brighter,and when less light reaches our eyes,it appears dimmer,creating the twinkling effect.
