Imagine that you’re part of a community living 10,000 years ago, and you’re sitting around a fire with your group in the evening. Above you, the sky is full of brilliant points of light. What are these points of light, and how did they get there?
You look at them and try to make sense of what you see. You imagine that the points of light, which we today refer to as stars, form pictures—and you create stories about the pictures. Today, those star pictures are called constellations. While we still tell the ancient stories about the stars, scientists today try to answer age-old questions about the universe.
