>>>December 28: Galileo discovers a new planet in the solar system

On February 13, 1633, Italian philosopher, mathematician and astronomer Galileo Galilei had to go to Rome to face the heretical court, accused of supporting the Copernican doctrine, claiming that the Earth spin around the Sun. Meanwhile, in Galileo's time it was believed that the Earth was the center of the universe and that all planets revolved around the Earth.

After that, he had to plead guilty to reducing the punishment. Finally, Pope Urban VIII decided to punish her heresy and make him subject to church supervision for the rest of his life. Galileo lived the rest of his life in the mansion in Arcetri, near Florence before his death in 1642.

Galileo was convicted of a heresy, protesting the teachings of the Roman Catholic Church.

Galileo Galilei is the son of a musician, born on February 15, 1564, in Pisa, Italy. He entered Pisa University in medicine, but then he switched to philosophy and mathematics. In 1589, he began to become one of the professors at the University of Pisa, during which time he also proved the theory of the falling speed of an object regardless of the weight of the object. To prove this theory, he experimented with dropping various objects from the Leaning Tower of Pisa.

From 1592 to 1630, Galileo began making a telescope, helping him to observe stars. During this time, he also discovered the four largest moons of Jupiter and Saturn's orbit. He discovered the Milky Way galaxy and published his research in 1610, Galileo received the support and acclaim of many scientists at the time.

Through observing the stars, Galileo discovers that the Earth is orbiting the Sun, as well as other stars, not the center of the universe. He further supported the Polish astronomer doctrine, Nicolaus Copernicus (1473-1573).

He was a supporter of Copernicus' theory, arguing that the Sun was central.

However, Copernicus' doctrine, arguing that the Sun was central, was contrary to the teachings of the Roman Catholic Church, which ruled Italy at that time. The Church thinks that Earth is the center of all things, not the Sun, so every doctrine that rejects this is considered heretical.

After Galileo was brought to trial before the Church court and heresy, all his documents and notes were banned from circulation among the people. It was not until 1992 that the Vatican officially acknowledged its mistake in pronouncing Galileo. And today, Galileo was honored as one of the scientists who made a great contribution to modern astronomy.
