Question

Quizplus · Accepted Answer

Twinkling of stars, also known as scintillation, is caused by the Earth's atmosphere distorting the light from the star. Advanced observing techniques, such as adaptive optics used in modern telescopes, can significantly reduce the effects of atmospheric distortion, thereby reducing the twinkling effect. This means that twinkling is not an inherent, unchangeable phenomenon.
