Why do you say "Galileo discovered a new universe"?

Galileo. As a pioneer of modern experimental science, Italian Galileo is not only a great Italian astronomer, but also a famous mathematician, physicist and philosopher.

Galileo's greatest achievement was the invention of the astronomical telescope in 1609. This astronomical telescope is also called galileo telescope. The invention of astronomical telescope is a leap in astronomy. Galileo used it to observe celestial bodies. He found that the surface of the moon was not as flat as what we saw with the naked eye, and he also drew the first map of the moon himself. 161065438+1October 7th, he discovered four moons of Jupiter, which proved the correctness of Gozzini's theory and Copernicus's theory was gradually accepted. In addition, Galileo also discovered sunspots, the rotation of the sun, the profit and loss phenomena of various stars, the laws of the movement of the moon, the formation of the Milky Way by countless stars and so on. These discoveries are of great significance in astronomy. They have opened up a new era in astronomy.

After continuous optimization and improvement, the magnification of galileo telescope has been continuously improved, and now it has been able to enlarge the physical object by 1000 times. With it, human beings have clairvoyance, and the secret of the universe is no longer a secret. Galileo telescope's invention made people no longer study the sun, moon and stars just by observing the stars with naked eyes.

In addition to the creation of the telescope, Galileo also left a large number of astronomical works, such as Star Messenger, Letters about Sunspots, Dialogue between Ptolemy and Copernicus, Talks and Mathematical Proof about Two New Sciences, etc. These are precious treasures for the development of astronomy.

Galileo's contribution is immeasurable. From people's evaluation of "Columbus discovered the new continent and Galileo discovered the new universe", we can see his position in the history of astronomy.

In addition, in order to commemorate Galileo's achievements, people named Io, Europa, Ganymede and Callisto as Galileo satellites.
