Here's why:
* The Sun's Brightness: The sun is incredibly bright. During the day, its light overwhelms the faint light from stars, making them invisible.
* The Earth's Rotation: The Earth rotates, causing the sun to appear to move across the sky. At noon, the sun is directly overhead, meaning the constellations that are visible at night are on the opposite side of the Earth.
To see constellations, you need to wait until after sunset when the sky is dark enough.
