@TimAkimoff I started digging around YouTube about the origins of our understanding of the Milky Way, because how can we know about the galaxy if we're in it? And that's when I learned you can see the disc extending across the night sky. It's beautiful and amazing. To be able to discern the shape of this immense thing, even if just a cross section, is somehow humbling. There it is, a billion stars spinning together in a pinwheel, and I'm just watching it from my backyard.
