Open space. From telescope to Marshound

For centuries, people wondered, looking at the stars: “But what, far, far, is in this black abyss?” The best minds of mankind tried to understand how our universe is arranged, what are the stars, the sun, the moon on? At different times, the ancient Greek scientists Eratosthenes, Hipparchus, Aristarchus of Samos nominated their hypotheses at different times - it was he who first suggested that it was not the sun that revolves around the Earth, but rather. It was incredibly bold, because the Earth was then considered the center of the universe around which the sun, planets and stars rotate. The geocentric system of Ptolemy existed until the 16th century, until the Polish scientist Copernicus proposed his heliocentric model of the solar system, where everything turns around the sun. The theory of Copernicus was proved thanks to one great discovery - the invention of the telescope. The first model of the telescope was designed by the Italian mathematician Galileo Galileo, it gave an increase in remote objects by 33 times. Observations of celestial bodies allowed Galileo to draw a conclusion that Copernicus was right, and everything really rotates around the sun. It was the appearance of the telescope that gave an impetus to the study of space and since then people can no longer stop, and space is still full of secrets and riddles
