Galileo's telescope changed astronomy in some major ways:
Discovering Celestial Bodies: With his telescope, Galileo found amazing things, such as the moons of Jupiter. This was important because it showed that not everything moved around the Earth. It supported the idea that the Sun was at the center of our solar system, not the Earth.
Observing the Moon: Galileo looked closely at the Moon and saw that it had mountains and craters. This was surprising because people used to think the Moon was perfectly smooth.
Sunspots and Venus: He also noticed dark spots on the Sun, proving that the Sun wasn’t perfect. Galileo discovered the phases of Venus too, which helped support the idea that planets move around the Sun.
Counting Stars: With his telescope, he saw many more stars than anyone had noticed before. This showed that the universe was much bigger and more complicated than people thought.
In summary, Galileo's telescope didn’t just give us a new tool. It changed how we understand the universe and laid the foundation for modern astronomy.
