Question

Name the phenomenon responsible for the observed twinkling of stars.Will this twinkling be observed by an observer on the moon

Answer 1

Refraction is the phenomenon responsible for the observed twinkling of stars.

This will not occur in the moon.

Answer 2

The phenomenon that causes stars to twinkle is atmospheric refraction. That is, the air above us is a big ocean of not very dense fluid that has a small bending effect on light that passes through it. If it were perfectly still, the light from a star would follow a path that stays put, and the star's image would appear stable. But the atmosphere is always moving; winds in every level of it cause slight density differences to move around, and different densities bend light by different amounts. And so the light rays from a star zig and zag as they head toward your eyes. That makes them appear to twinkle.

This twinkling is not observed by an observer on the moon,since we all know moon has no air
