The invention of the telescope in the early 17th century made it possible for astronomers to see things that had never been seen before.  This college-level course will look at how new observations —from Galileo’s discovery of the moons of Jupiter to Hubble’s discovery of the expanding universe—challenged accepted ideas about the size, age and the very nature of the universe.
