Galileo, the Impact of the Telescope, and the Birth of Modern Astronomy

June 2011
Proceedings of the American Philosophical Society;Jun2011, Vol. 155 Issue 2, p134
Academic Journal
The article examines astronomer Galileo Galilei's contributions to the development of modern astronomy, with emphasis given to his use of the telescope when conducting astronomic observations. The author begins by explaining Galileo's belief in the heliocentric model of the Solar System. He goes on to detail how Galileo's telescopic observations of the Moon, the orbits of Jupiter's satellites, and the phases of Venus helped convince him of the validity of Copernican cosmology.
