Stars are different colors, too, not just white. They’re blue, red, purple, green, yellow. And there are billions of them. The constellations look like constellations. You can make out the shapes and see what early astronomers were getting at with their descriptions. The Southern Cross was my favorite. And the moon feels like it’s right there. It’s not a two-dimensional white disc anymore. It looks like a ball, a gray planet. You can see the mountains and craters clearly. It feels closer than it is. You can see the gas clouds of the Milky Way. You’re in the greatest planetarium ever built.
