We Found a Possible Exoplanet in Another Galaxy! (LSP #215)
If life existed on Earth, my ten-year-old self figured, then it had to exist elsewhere. If our Sun had oodles of planets and moons whizzing around it, then other stars had to have them as well. And on those planets, who knew what might exist? It seemed far more likely to me that at least some other planets hosted life — and more than that, intelligent life — than that none possibly ever could.
