stars twinkle because of turbulence in the atmosphere of the earth. as the atmosphere churns, the light from the star is refracted in different directions. this causes the star's image to change slightly in brightness and position, hence twinkle. this is one of the reasons the hubble telescope is so successful: in space, there is no atmosphere to make the stars twinkle, allowing a much better image to be obtained. planets do not twinkle the way stars do. in fact, this is a good way of figuring out if a particular object you see in the sky is a planet or a star. the reason is that stars are so far away that they are essentially points of light on the sky, while planets actually have finite size.

the size of a planet on the sky in a sense averages out the turbulent effects of the atmosphere, presenting a relatively stable image to the eye. the scientific name for the twinkling of stars is stellar scintillation (or astronomical scintillation). stars twinkle when we see them from the earth's surface because we are viewing them through thick layers of turbulent (moving) air in the earth's atmosphere. stars (except for the sun) appear as tiny dots in the sky; as their light travels through the many layers of the earth's atmosphere, the light of the star 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).
