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.

The change in intensity of light coming from the stars is called twinkling of stars. The twinkling of stars occurs due to atmospheric refraction of star's light. Hence, the star light reaching our eyes change continuously and stars appear to twinkle.
