twinkling of stars is caused by refraction
The effects of "twinkling" is caused by the Earth's atmosphere.
scintillation
The twinkling of the stars is caused by changes in temperature and pressure in our atmosphere. Therefore it is random, and not a meassure of the stars.
No. The twinkling is caused by the light of the stars being distorted by Earth's atmosphere, which is in constant motion.
scintillation
This phrase likely refers to the twinkling effect observed when looking at distant stars through Earth's atmosphere. The twinkling, or shivering, of blue stars is caused by the turbulence in the atmosphere bending and scattering the starlight as it reaches our eyes.
Our atmosphere changing (filters) the starlight being viewed from Earth. It is said that the sparkling (twinkling) of the stars is caused by the dust floating in our atmosphere.
The only difference of the twinkling caused by the distortion of light due to the earths atmosphere which is not present in a vacuum.
The distortion of light from stars, causing them to twinkle, is due to the turbulence in Earth's atmosphere. As light passes through the varying densities of the atmosphere, it gets refracted in different directions, leading to the twinkling effect. Telescopes on high mountains or in space, above most of the atmosphere, can reduce this effect.

Very shiny
Stars are not twinkling really. It is because of the atmosphere of the earth due to which they appear twinkling. However if they are seen from above the atmosphere of earth then they appear stationary.
