why do stars twinkle plzz tell me fast its urgent
Answers
Stars do not really twinkle, they just appear to twinkle when seen from the surface of Earth. The stars twinkle in the night sky because of the effects of our atmosphere. When starlight enters our atmosphere it is affected by winds in the atmosphere and by areas with different temperatures and densities.

Answer :
We know that the stars emits their own light called starlight due to this they shine on the sky . In other words twinkling is not caused by the stars which are super constant in their brightness it is caused by the earth's atmosphere, as the light from a star travels towards the earth through the atmosphere it passes through many layers of air varying temperatures and densities . Each of the boundaries of those layers of air refracts the light bending in a slightly direction from moment to moment. So the starlight zigs and zags passes from the star to the telescope on the ground .From our perspective this makes the star appears to be twinkle .
