Nicolaus Copernicus's heliocentric model. Copernicus studied at Bologna University during 1496–1501, where he became the assistant of Domenico Maria Novara da Ferrara.He is known to have studied the Epitome in Almagestum Ptolemei by Peuerbach and Regiomontanus (printed in Venice in 1496) and to have performed observations of lunar motions on 9 March 1497.
On the Revolutions of the Heavenly Spheres by Nicolaus Copernicus, which explains Copernicus' theory of heliocentrism: that the Sun, rather than Earth, lies in the center of the universe; Two New Sciences by Galileo Galilei explains Galileo's discoveries in physics
Copernicus's Toruń birthplace (ul. Kopernika 15, left).Together with no. 17 (right), it forms Muzeum Mikołaja Kopernika.Nicolaus Copernicus was born on 19 February 1473 in the city of Toruń (Thorn), in the province of Royal Prussia, in the Crown of the Kingdom of Poland, [10] [11] to German-speaking parents.
Galileo Galilei observed the phases of Venus in December 1610, an observation which supported Copernicus's then-contentious heliocentric description of the Solar System. [13] He also noted changes in the size of Venus's visible diameter when it was in different phases, suggesting that it was farther from Earth when it was full and nearer when ...
However, the idea that the Earth moved around the Sun was doubted by most of Copernicus' contemporaries. It contradicted not only empirical observation, due to the absence of an observable stellar parallax, [79] but more significantly at the time, the authority of Aristotle. The discoveries of Kepler and Galileo gave the theory credibility.

The historian Wrightsman put forward that Osiander did not sign the letter because he "was such a notorious [Protestant] reformer whose name was well-known and infamous among Catholics", [9] so that signing would have likely caused negative scrutiny of the work of Copernicus (a loyal Catholic canon and scholar).
Galileo observed the phases of Venus's appearance with the telescope and was able to confirm Kepler's first law of planetary motion and Copernicus's heliocentric model, of which Galileo was an advocate. [75] Galileo claimed that the Solar System is not only made up of the Sun, the Moon and the planets but also comets. [76]
