star twinkle at night.why?​

Answer 1

Answer:

Answer 2

$\huge\mathcal\color{teal}{Answer :- }$

When light from a distant source (a star) passes through our turbulent (moving air) atmosphere, it undergoes refraction many times. When we finally perceive this light from a star, it appears to be twinkling! ... It is because there are more layers of the atmosphere between you and the star in this direction.
