Today we are in modern astronomy research but before this, many scholars sacrificed their lives for it and were immersed in astronomy research all their lives.

Galileo Galilei was the first of many such astronomers. He is very fond of gazing at the sky. Galileo Galilei is the epitome of many scientists who want to see what lies beyond this earth. A person who was used to looking at the sky with the naked eye wanted to look beyond it so the telescope was made by him.

Since the invention of the telescope, his job has been to continuously gaze at the sky through it. Exploring space through a telescope was one of his favourite things. One night the person who was looking at the sky for a long time through the telescope thought that he could sleep from now on, so he turned the telescope to one side and by chance the planet Jupiter appeared to his eye and there he also saw a miracle.

The miracle he saw was a halo. Jupiter can be seen through a telescope at night and looks like a bright star. He was not surprised to see Jupiter, he was surprised to see three small stars near Jupiter.

He had never seen those stars before, he saw stars that no one else in the world had seen and a mixture of wonder and joy overwhelmed him. Galileo's research got a new momentum.

Every night he turned his telescope towards Jupiter. Sometimes three stars and sometimes two stars were visible. Sometimes three stars became four stars. They were all visible near Jupiter.

They did not stay in one place. They moved. One day, as usual, Galileo was looking at Jupiter through his telescope when suddenly he jumped into oblivion because he discovered the secret of some of the stars near Jupiter.

He understood that the natural satellites revolved around the planet Jupiter just as the moon revolved around the Earth. Of the 4 natural satellites only two were visible, Galileo determined that the other two must be hidden behind Jupiter.

 


Scientists think that asteroids orbiting a planet are its moons, and in line with their theory, Jupiter's side stars are actually its moons. Galileo, who discovered that Jupiter's moons revolved around the Sun, thought that the planets might also be a family of planets orbiting the Sun and that the Earth might be one of those families.

This idea of ​​Galileo's idea formed in his study guided other scientists at a time when nothing was known about the sun. Galileo told other scientists an interesting story about the moons orbiting Jupiter, and many of those scientists were amazed, but they did not accept Galileo's idea that Earth could be one of the planets.

It took many years for them to realize that it was true that the Earth and the other planets revolved around the Sun. It was confirmed that the planets revolved around the Sun as a family just as the moons revolved around Jupiter. It was in that miracle that they began to discover the truth. Galileo's fame reached its peak and the way he showed other scientists inspired space exploration.
