From the fifteenth century Europe awakens from its medieval lethargy. The era we know as "The Renaissance" begins.
In astronomy, Nicolás Copernicus rejected the geocentric universe and proposed the heliocentric theory, with the Sun at the center of the Solar System and the Earth, just like the rest of the planets, revolving around it. He continued to use circumferences and simplified the calculations of the previous theories.
For his part, Tycho Brahe spent his life collecting data concerning the movement of the planets in the largest astronomical laboratory of that time. His measurements were of extraordinary precision despite not having the help of the telescope.
Johannes Kepler was an assistant to Brahe and used his data, together with Copernicus theory, to state the laws that bear his name and describe the motion of the planets in a cinematic way.
Galileo Galilei, while Kepler was developing his laws, studied the stars with a telescope. He discovered the craters and mountains of the Moon, the four great satellites of Jupiter and defended the Copernican system. Scientific astronomy had begun.
Since then, the discoveries have been happening continuously and at a growing rate. Four centuries later, with the arrival of computers, space travel, Internet and new technologies, a deep knowledge about the Universe that grows day by day has been achieved.
