History of TelescopesMaps to the Stars: A History of the Telescope
The scientific instrument that revolutionized astronomy
When Galileo first turned a telescope toward the sky and observed a celestial object, he could never have dreamed that humans would one day set foot on it. At just 30 power magnification, the moon was just clear enough for him to sketch some detailed drawings of its mountains and craters. Galileo created larger, more complex telescopes, which bolstered the study of the cosmos for Isaac Newton and other physicists who followed. Today, the telescope allows everyone, from backyard astronomers to astrophysicists at observatories, to extend the boundaries of the known universe.
