Planetariums

A planetarium is a building with a dome where a projector shows the night sky and space. Visitors can explore stars, planets and constellations indoors.

Modern planetariums can show the sky as it looked thousands of years ago.

Planetariums let people explore space even when the sky is cloudy or the city lights are bright.

Many planetariums also show shows about space travel, the Big Bang and the life cycle of stars. They are a fun way to learn about astronomy and to spark an interest in science.
