Why do stars twinkle?
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.
Why do we see the same stars every night?
The stars are not fixed, but are constantly moving. If you factor out the daily arcing motion of the stars across the sky due to the earth’s rotation, you end up with a pattern of stars that seems to never change.
