Why do stars twinkle?
Choose one:
A. The stellar surface where the light is emitted is very turbulent.
B. Our eyes are constantly moving.
C. Stars are constantly changing their brightness.
D. The distribution of absorption lines in their atmospheres is changing.
E. The motion of Earth's atmosphere creates the appearance of twinkling.

Answer (2)

Stars twinkle due to the motion of Earth's atmosphere, which refracts their light as it travels through various atmospheric layers. This results in an appearance of fluctuating brightness and position. Other explanations do not accurately describe the twinkling phenomenon. ;

Stars twinkle due to the motion of Earth's atmosphere, which causes the light traveling from stars to bend as it passes through different air layers. This results in the appearance of fluctuating brightness and position. Thus, the correct answer is Option E: The motion of Earth's atmosphere creates the appearance of twinkling.
