Watching the stars move
It’s the middle of the day. The lights around you fade. Soon, all you can see are faint stars glimmering overhead. Slowly, the moon rises above the horizon and moves across the sky. But how can you see all this in the middle of the day? It’s easy. You’re in a planetarium.
A planetarium is like a special cinema. Instead of showing films on a flat screen, the projector in a planetarium shows pictures of planets, stars, and moons on a domed ceiling. Your chair tilts towards the dome. Stars and planets seem to move across the sky. They can move faster than in real life because the projector controls them. In just a few minutes you can see how the stars and planets move across the sky all night. You can even see the movement of stars through a season or a year.
