When the human being discovered that the planet he inhabited was not alone in the universe, he had an enormous eagerness to know how everything around the earth was shaped. Astronomy had philosophers of the scope of Aristotle, one of its promoters . Then he was followed by men who transformed the vision of the space we inhabit. Galileo Galilei, Johannes Kepler, Nicolás Copernicus, are some of the names that have stood out in the study of the cosmos. Many of them even had to confront the prevailing conceptions of their time, to the point of becoming almost marginal. Today, astronomy has become a science with a deep life of its own.
The section that the WhatAsker dedicates to astronomy , has definitions, theories and laws . Here you will be able to know the different bodies that inhabit the universe: planets, stars, comets, satellites, the laws that govern their movements , as well as introducing us to the trips that have allowed us to expand the frontiers of knowledge of the universe. In each topic addressed, readers will be able to find excellent graphic material that allows them to expand their knowledge.
