Science Fridays in the Planetarium: Two Small Pieces of Glass

Friday, December 20 | 6:00 & 7:00 PM

Gaileo 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. His two small pieces of glass revealed a Universe that was far more complex than previously assumed. Telescopes have advanced considerably since Galileo’s time. Humanity now has large observatories and even a couple in outer space. Two Small Pieces Of Glass shows how telescopes work; and how astronomers have used them to scrutinize the structures within our cosmos.
