Twinkle, twinkle, little star,
How I wonder what you are.
Up above the world so high,
Like a diamond in the sky.
Twinkle, twinkle, little star,
How I wonder what you are!
My friend asked my why do stars twinkle? And I was stupefied by the question, why haven't I actually thought of that before? I thought about that and couldn't come up with an answer, this shows that my brain is too rigid!
Stars twinkle because of turbulence in the atmosphere of the Earth. As the atmosphere churns, the light from the star is refracted in different directions. This causes the star's image to change slightly in brightness and position, hence "twinkle."
