Galelio’s telescope
Location: Surat
Description of the Exhibit/ working Principle
Historical Background:  In 1609, 45 years old Galileo introduced telescope in observational astronomy and created an epoch-making history in the field of science as well as in the human society. 

His boldly turning his telescope to the sky led him to found observational evidence of Copernican theory of the Universe. His observations encouraged him to print a 40-page pamphlet Sidereus nuncius (The starry messenger). In this pamphlet he announced the existence of myriads of new stars, the uneven surface of moon with full of hollows, lofty mountains and deep valleys. The most spectacular observation was four moons orbiting Jupiter. The discovery of Venus, mercury orbiting something other than Earth dealt a blow to the then-accepted Geocentric model of the universe.
