Stars are like cosmic flashlights. They help scientists see how far away things are and what they're made of, just like a flashlight can show you the shape of a room in the dark. If we look at how stars shine, we can learn about the whole universe.
Examples
- The color of a star tells scientists if it's hot or cool, just like the color of fire shows its intensity.
- When we look at a star, it's like looking back in time because its light has traveled across space for years.
