Seventeenth-century Italian scientist Galileo was, so as as we know, the first to use a new invention called the telescope to peak at celestial objects. When he turned his instrument to the Moon in 1609, he was astounded at what he saw. "The Moon is not smooth and uniform," he wrote, "but uneven, rough and full of cavities." With one glance, Galileo had smashed the centuries-old belief that heavenly bodies were perfectly formed and precisely spherical!
