Step-by-step explanation:
The main difference between the day sky and night sky is the amount of light that is present.
During the day, the sky appears blue because of the way that sunlight interacts with Earth's atmosphere. As sunlight enters the atmosphere, it is scattered in all directions by the gases and particles in the air. Blue light is scattered more than other colors because it travels as shorter, smaller waves. This is why the sky appears blue during the day.
At night, when the sun has set, there is no direct sunlight to scatter in the atmosphere. Instead, we see the light of stars, planets, and other celestial objects that are visible from Earth. The darkness of the night sky allows us to see more clearly the beauty of the stars and the Milky Way.
Additionally, the position of the stars and constellations in the night sky changes throughout the year, as the Earth rotates on its axis and orbits around the sun. In contrast, the position of the sun in the sky changes throughout the day, as the Earth rotates.
