Studying the constellations and learning the sky is a great way to get a visceral sense of our place in the universe. When you can't tell one patch of sky from another, the brain doesn't need a fancy model for the reality of it, and you can go around with a kind of subconscious "flat sky" in your head. But when you start to piece the constellations together, and it all connects up around you, that's transformative. Space stops being something that's "up there", and becomes a thing that surrounds you. It's a strange sensation when it first hits you, and well worth the time to achieve it.
