I’m so fucking emotional about the 7 planets of Trappist 1.
Imagine living so close to another habitable planet that it’s like a moon in the night sky. Imagine that for six other planets. Imagine hypothetical aliens in their equivalent of the renneisance, mapping orbits and studying the sky, starting to notice each other through their telescopes. God that’s so cool. Imagine knowing something is there so soon and slowly working towards getting to know them.
Heck, even just being able to see your neighbour planets that close, even without life, makes the solar system so obviously devastatingly lonely by comparison.
