Dear Student

Stars twinkle due to atmospheric refraction of light from the stars and changing density of air around the earth.

As light from a star races through our atmosphere, it bounces and bumps through the different layers, bending the light before you see it. Since the hot and cold layers of air keep moving, the bending of the light changes too, which causes the star's appearance to wobble or twinkle.
