The mysteries and immenseness of the Universe has intrigued man like nothing more right since the dawn of time. However, it wasn’t until the Renaissance period that the technological advancements fostered humankind in a new era of science and discovery. The initial boost came from the invention of the telescope. Based only on uncertain descriptions of the first practical telescope which Hans Lippershey tried to patent in the Netherlands in 1608, Galileo, in the following year, made a telescope with about 3x magnification. He later made improved versions with up to about 30x magnification. On 25th August 1609, he demonstrated one of his early telescopes, with a magnification of about 8 or 9, to Venetian lawmakers. His telescopes were also a profitable sideline for Galileo, who sold them to merchants who found them useful both at sea and as items of trade.
