Since … Australian scientists have developed a new type of sensor to measure and correct the distortion of starlight caused by viewing through the Earth’s atmosphere, which should make it easier to study the possibility of life on distant planets. This causes the star's image to change slightly in brightness and position, hence "twinkle." Once the light from a star enters the Earth's atmosphere, each of its rays get refracted, causing a slight change in the direction due to various temperature and density layers of the atmosphere. Stars twinkle when we see them from the Earth's surface because we are viewing them through thick layers … Simultaneously due to the movement of air, the refractive index of layers of atmosphere keeps on changing, i.e., the apparent position of star keeps changing. Distance is the main reason stars twinkle more conspicuously than the planets in our solar system. (a) Refraction of light by different layers of varying refracting indices. He also helps us out with the odd cosmology question. Short answer: Stars twinkle because they’re so far away from Earth that when light from the stars passes through the atmosphere, it is bent countless times due to refraction, making it look … You can visualize that light moves in a zig- zag path instead of a straight path to your eyes in case the Earth didn't have an atmosphere.
