USA HISTORY

Detailed explanation-1: -The stars twinkle in the night sky because of the effects of our atmosphere. When starlight enters our atmosphere it is affected by winds in the atmosphere and by areas with different temperatures and densities. This causes the light from the star to twinkle when seen from the ground.

Detailed explanation-2: -Stars appear to twinkle because as light from those stars passes through our atmosphere, it is bent and distorted by varying temperatures and densities of air. There is even a scientific term for stars’ twinkling, and that’s ‘atmospheric scintillation’.

Detailed explanation-3: -Why do stars shine at night? They glow because the gas inside them undergoes a process known as “nuclear fusion, ” which brings two atoms together to form a different type. The amount of energy forms the light that can be seen.

Detailed explanation-4: -These apparent star tracks are in fact not due to the stars moving, but to the rotational motion of the Earth. As the Earth rotates with an axis that is pointed in the direction of the North Star, stars appear to move from east to west in the sky.
