A telescope collects light — the bigger the mirror, the farther you see. Hubble has photographed billions of galaxies since 1990, and the James Webb telescope (2021) sees in infrared the first galaxies ever — light that traveled 13+ billion years. On Earth, the strongest telescopes stand in mountains and deserts — far from city lights.
