The Renaissance of Astronomy

The Renaissance of Astronomy

Astronomy took a drastic turn in the 16th century. The geocentric theory was replaced by the heliocentric system, with the Sun in the center. The invention of the telescope allowed much more precise observations that corroborated this new theory.

The cultural and scientific renaissance accelerated the changes and there were many important discoveries. The long medieval lethargy is over. The new astronomers used increasingly better instruments, applied scientific methods and, above all, they could spread their studies thanks to the diffusion of the printing press.

Renaissance astronomers discovered how the Solar System works, described the orbits of the planets, analyzed the light, knew deep space, observed the stars, ... Astronomy advanced as never before.

This period is full of illustrious names. Here we present some of the most relevant.
