The Milky Way does look a bit different each night because we’re moving through it and the view changes with the weather and our own tiny wobble in space. The glow comes from countless stars, dust, and gas clouds all spread out in a thin disc. As we orbit the center, our angle shifts, so the brightest parts and the faint hazy bands change just a little. It’s a quiet reminder that even the big things are in motion, and every night gives us a new, gentle painting to look at.
