Hailey AlexanderWhen the sun sets and the sky darkens, the light from stars becomes more prominent and visible to us. Stars are visible in the sky at night because they emit light, which travels through space and reaches our eyes. During the day, the brightness of the sun overwhelms the light from other stars, making them difficult to see.
