Why do stars twinkle during the day?

Introduction:
Stars are celestial bodies that emit their own light. They appear as tiny, twinkling points of light in the night sky. However, stars do not twinkle during the day. This is because the brightness of the sun outshines the light of the stars, making them invisible during daylight hours. Let's explore this phenomenon in detail.

Explanation:
The twinkling of stars is caused by the Earth's atmosphere. When starlight passes through the Earth's atmosphere, it undergoes refraction due to the varying density of air at different altitudes. This refraction causes the starlight to change direction, leading to the twinkling effect that we observe from the ground.

Why stars twinkle at night:
At night, when the sun sets and the sky becomes darker, the amount of atmospheric turbulence decreases. This results in less refraction of starlight, causing the stars to appear more stable and twinkle less. Hence, stars twinkle more prominently during the night.

Why stars do not twinkle during the day:
During the day, the sun is the primary source of light in the sky. The intensity of sunlight is much greater than the light emitted by stars. The brightness of the sun overwhelms the relatively dim light of the stars, making them invisible to the naked eye.

Atmospheric conditions:
The Earth's atmosphere scatters sunlight in all directions, causing the sky to appear blue during the day. This scattering of sunlight reduces the contrast between the stars and the background sky, further making it difficult to observe the twinkling of stars during daylight hours.

Conclusion:
The twinkling of stars is a fascinating phenomenon caused by the Earth's atmosphere. During the day, the brightness of the sun outshines the light of the stars, making them invisible. However, during the night, when the atmospheric turbulence decreases, the stars become more visible and twinkle in the dark sky.

Stars actually do not twinkle,we see them twinkling because many heavenly bodies pass in front of them consecutively and then we see them,then we don't we see them and then... hence they appear to be twinkling.
