answered-by-expert Expert Answer

As the light from stars travels through the many layers of the Earth's atmosphere, it is bent (refracted) many times and in random directions (light is bent when it hits a change in density - like a pocket of cold air or hot air). This random refraction results in the star winking out (it looks as though the star moves a bit, and our eye interprets this as twinkling).
