This year marks the 400th anniversary of the first use of an astronomical telescope by Galileo Galilei. Though famous for his telescopic observations of Jupiter's moons, Galileo wasn't the inventor of the telescope. In this segment, we'll talk about the early days of scientific optics, including the work of eyeglass maker Hans Lippershey, who applied for a patent on a spyglass in October 1608.
