Civilizations as the Aztec, the Mayan and inca, as well as Egyptian, Chinese and Greek reached a degree of expertise that are taken by fundamental for the further evolution of the discipline. In this sense, it is considered the oldest science, and it has been essential in the development of science, such as mathematics or physics disciplines.

Some astronomers of great importance in the history have been Claudio Ptolomeo, Nicolás Copérnico, Johannes Kepler and Galileo Galilei.

Astronomy and astrology

Although astronomy and astrology in the beginning were terms that could be used as synonyms, today appointed distinct disciplines. Currently, astronomy has been developed as a scientific discipline that deals with the study of the stars, his movement and the laws that govern them, while astrology was maintained over time as a system of beliefs and superstitions related to the influence that is attributed to the movement of the stars on the character of the people and historical events. Both Sciences were separating and differentiating from Renaissance, thanks to the prevalence of Rationalist thinking.
