And as we've learned over the centuries, since Galileo Galilei, the Italian scientist, first turned, in that time, a two-inch, very small telescope, to the sky, every time we have built larger telescopes, we have learned something about the universe; we've made discoveries, without exception.
Tal como aprendemos ao longo dos séculos, dende que Galileo Galilei, o científico italiano, apuntou cara ao ceo  cun pequeno telescopio de 5 centímetros, sempre que construímos  telescopios maiores, descubrimos algo sobre o universo; fixemos descubrimentos, sen excepcións.
