Two Small Pieces of Glass
Galileo did not invent the telescope, but he was the first person to use the newly invented device to observe the sky. Through these observations the Italian philosopher-scientist concluded that the heavens were not perfect and immutable: he observed lunar mountains, phases of Venus, Jupiter’s moons, and even sunspots. The two small pieces of glass revealed a Universe that was far more complex than previously assumed. The Two Small Pieces of Glass program shows how telescopes work; and how astronomers have used them to scrutinize the structures within our cosmos. Show length: 23 minutes
