Eyes on the universe

August 25, 1609 Galileo Galilei presented an eight-powered instrument to the Venetian Senate. His were not the first, nor the only ones. Hans Lipperhey is considered the inventor and holds the first patent, in 1608. Galileo expanded the design. His telescopes and observations are the best known.
The telescope was one of the central instruments of what has been called the Scientific Revolution of the seventeenth century. It revealed hitherto unsuspected phenomena in the heavens and had a profound influence on the controversy between followers of the traditional geocentric astronomy and cosmology and those who favored the heliocentric system of Copernicus.
