Get ready to journey back in time and meet a scientist whose discoveries shone as brightly as the stars. It’s time to explore the fascinating world of Galileo Galilei!

Galileo Galilei was a brilliant Italian scientist who lived in the 16th and 17th centuries. He was a curious and inquisitive mind, always questioning how the world worked. His passion for knowledge led him to become one of the greatest scientists in history.

One of Galileo’s most famous discoveries was about the sky above us. He used a telescope, a 

remarkable invention at the time, to observe the heavens. Galileo gazed at the moon and discovered that its surface wasn’t smooth as people once believed. It had mountains and craters, just like Earth!

Galileo also turned his attention to the stars and planets. Through his telescope, he saw things that no one had ever seen before. He observed the four largest moons of Jupiter, now known as the Galilean moons, and realized that they orbited the giant planet, just like our moon orbits Earth.

But Galileo’s discoveries didn’t always go down well with everyone. He supported the idea that Earth revolves around the sun, which was a controversial idea at the time. People believed that Earth was at the center of the universe, but Galileo’s observations and evidence suggested otherwise. His ideas challenged the status quo and caused quite a stir!
