The discovery of telescope marks a fundamental step in the history of mankind. The celestial observations allowed by this instrument will indeed completely upset the conception of the Universe that scientists had until then. Most historians attribute his invention to Hans Lip-pershey, a manufacturer of glasses Dutch. In 1608, he combined a convex lens and a concave lens to create the first spotting scope.
The following year, Galileo, the brilliant Italian inventor, is the first to point one (of his own making) on the skies. His observations allow him to discover the satellites of Jupiter, the mountains of Moon, the phases of Venus, the stains on the Sun and countless stars invisible to the naked eye. After having rested it, he sweeps away the thesis of the immutability of the cosmos, formulated in Antiquity by Aristotle. And, above all, it validates the Copernican theory, which wants the Earth to revolve around the Sun, and not the other way around.
Therefore, modern astronomy, which will lead to the XXe century discovering the big Bang (the original explosion that created a Universe in continuous expansion), takes off.
