Most stars burn steadily, and if we could see them from space they would not be twinkling at all. This is because as the light from a star passes through the earth's atmosphere, it is bent by changes in the air temperature. This makes the light appear to flicker. Because of this effect, astronomical observatories are situated on mountain tops. Higher up, the air is thinner and it is therefore less likely to cause this twinkling effect.
