In late 2007, the United Nations (UN) 62nd General Assembly proclaimed 2009 the International Year of Astronomy, celebrating the first astronomical use of the telescope by Galileo -- a momentous event that initiated 400 years of astronomical discoveries and triggered a scientific revolution which profoundly affected our worldview. 

The Planetarium is participating in this extraordinary worldwide event by presenting this Show. Produced to engage and appeal to audiences of all ages, Two Small Pieces of Glass traces the history of the telescope from Galileo's modifications to a child's spyglass – using two small pieces of glass – to the launch of NASA's Hubble Space Telescope and the future of astronomy. It explores the wonder and discovery made by astronomers throughout the last 400 years.
