Question

Why do you think stars are appearing like this?

Answer 1

Answer:

Scintillation, or the "twinkling" we see of stars in the sky, is due to motions in the earth's atmosphere. ... So it is very much connected to our atmosphere and its weather. When we look at a star from the surface of the earth, we are also looking through the various layers of the atmosphere.

Answer 2

Answer:

Stars make their own light, just like our sun (the sun is a star — the closest star to Earth). But the stars are very, very far away from our solar system so they appear to be very tiny to us, even though up close they are large. ... They reflect the light of the sun in the same way our moon reflects sunlight.
