Learning path
In the order the concepts build on each other.
- StarsLockedThe tiny shining dots in the night sky are stars - huge, hot, glowing balls of gas that make their own light, like the Sun. They look tiny only because they are extremely far away. The Sun is a star too, the one close to us.Opens after: The Sun, Day and night
- GalaxiesLockedStars are gathered in enormous groups called galaxies, each with billions of stars. Ours is the Milky Way, with hundreds of billions of stars; every star we see at night is in it, and on a dark night far from towns it shows as a pale band across the sky. The Sun is one of its stars, the one closest to us.Opens after: Stars
