Question

why do stars twinkle at night?

Answer 1

Hey mate ^_^

On a clear night, light coming from star gets refracted in atmosphere and reaches to our eye. Thus image of star appears somewhat displaced from its actual position.

Since, atmosphere has both cold and hot air and by changing width of these layers of air light ray bends less or more.

So, image of star appears changing its position. This is twinkling of star.

stars twinkle because of the turbulence in the atmosphere of the earth.as the atmosphere churns , the light from the star gets refracted in different direction. this causes the star's image to change and slightly bright and hence appears to twinkle
