Question

Why do stars twinkle in clear night

Answer 1

The twinkling of stars in our night sky is down to the Earth's atmosphere. As light from the stars travels towards Earth it can easily move in a straight line, but once it starts travelling through the Earth's atmosphere it gets bounced around in different directions by the particles in the air.

Answer 2

Answer:

In fact, most of the stars are shining with a steady light. The movement of air (sometimes called turbulence) in the atmosphere of Earth causes the starlight to get slightly bent as it travels from the distant star through the atmosphere down to us on the ground. ... To our eyes, this makes the star seem to twinkle$\huge\bold{\pink{Høpê } \green{ \: ït} \red{ \: hêlps \: } \purple{uh♡}}$@DevilQueen
