Le 4 Stagioni del Cuore - Damiano Martorelli
E-book available on e



Astronomy has its remote origins in the folds of time, when the first man turned to the sky, questioning himself what were these bright dots that appeared at night, or what was that object that depending on days, was full bright or only partially.

Astronomy takes its name from the greek: άστρων νόμος is literally the "law of the stars", hence the current name of this science whose subject is the observation and explanation of space events. It properly examines the origins and evolution, and physical, chemical and temporal porperties of objects that make up the Universe and can be observed on the celestial sphere.

For many centuries, astronomy and astrology (one pseudo-science which argues that the celestial phenomena has an influence on events and in particular on human lifes) have gone hand in hand: the observation and forecasting the movement of celestial objects that could be observed with the naked eye were made by the early astronomers, typically represented by the priests of a specific religion. The purpose was twofold: first to create calendars, which are essential for the organization of social life and agricultural-pastoral activities; on second place, to precisely understand the effects that it was thought the stars had on human activities (hence the study of the constellations and all the theories on them).

Only with the Renaissance finally the two "areas" will be distinguished, especially with the refutation of the geocentric theory (or Ptolemaic) by Copernicus, and the formalization and distribution of the Galilean scientific method, based on experimental testing of submissions . Despite the obscurantism of the ecclesiastical realities of the time, and the recantation of the Copernican theory (heliocentric) that Galileo was forced to do, the method and its Galilean discoveries spread across Europe, opening the road to modern astronomy.
