While there he discovered a natural talent for math, and eventually left medical school to pursue mathematics. In 1609, Galileo learned about the spyglass, a new invention helping people see distant objects by making them appear closer. This fascinated Galileo and led him engage his mathematics and engineering talents in a quest to build a more advanced spyglass. He ended up inventing the first telescope. Using the new device, Galileo became the first person to observe the Moon up close. He discovered that its surface wasn’t smooth, but actually mountainous and pitted like Earth! Continuing his astronomical research, he would use his telescope to establish that small moons circled Jupiter, and he closely observed the rings of Saturn and the phases of Venus.
