Why do we see stars in the night sky?
We see stars at night because they make their own light, and when the sky gets dark, that light can reach our eyes.
Stars are really huge, hot balls of gas. Energy is always being made inside them, so they make their own light, just like the Sun. The Sun is actually a star too — it only lights up the daytime sky because it is so close to us.
During the day, the Sun's light is so strong that it hides the light from other stars, so we can't see them. When night comes, the Sun goes down and the sky turns dark, so the faint light from far-away stars can finally reach our eyes.
Stars are so far away that their light looks like tiny dots. Some stars are even bigger and brighter than the Sun, but because they are so far away, they only look like tiny sparkling points in the sky.
