First published Fri Mar 4, 2005; substantive revision Wed May 10, 2017. Galileo Galilei (1564â1642) has always played a key role in any history of science and, in many histories of philosophy, he is a, if not the, central figure of the scientific revolution of the 17th Century. His work in physics or natural philosophy, astronomy, and the methodology of science still evoke debate after over 400 years.
Galileo and the Telescope. The science of astronomy took a huge leap forward in the first decade of the 1600s with the invention of the optical telescope and its use to study the night sky. Galileo Galilei did not invent the telescope but was the first to use it systematically to observe celestial objects and record his discoveries. His book, Sidereus nuncius or The Starry Messenger was first published in 1610 and made him famous.
