A Polish astronomer who proposed the heliocentric model of the solar system Father of Modern Astronomy The Tychonic System Tycho designed his own instruments, including the new astronomical sextant and a building-sized quadrant King Frederick II offered an observatory to Tycho, and it was named Uraniborg observatory in 1576 Imperial astronomer in Prague after accepting the invitation from the Holy Roman Emperor Tycho's observations of the Sun proved the inaccuracy of the Julian calendar, which led, in 1582, to the creation of the Gregorian calendar. Tycho also completed a star catalogue, which positioned over 800 stars, the first new catalogue since Ptolemy. His major contribution in astronomy is that he made a very accurate measurements of star and planet positions using his naked eye An Italian scientist who made significant contributions to modern astronomy. He improved upon the telescope and observed celestial bodies, supporting Copernican heliocentrism. Three Laws of Planetary Motion Supported a heliocentric (Copernican), not geocentric view He observed the first variable star – one that varies in brightness over time. An astronomer who compiled an atlas of the Moon. Isaac Newton was an English physicist and mathematician who formulated laws of motion and universal gravitation. His work revolutionized our understanding of how celestial bodies move. Theory of Special Relativity (1905) Theory of General Relativity (1915)
