VIII/ Astronomy is the studying of the planets and the stars, and people who study astronomy are astronomers. Telescopes help people to learn about our solar system. In 1609, Galileo used one of the first telescopes to look at the night sky. He saw mountains and craters on the Moon, and four moons around Jupiter. The first telescopes were very small. Later, people made' bigger telescopes, and they discovered new planets and moons.
When Galileo looked at a bright area in the night sky, he discovered that it was made of many stars. Later, people discovered that this is the center of our galaxy, the Milky Way. For a long time, astronomers thought that the Milky Way was the only galaxy in the universe. Then in 1930, an American astronomer called Edwin Hubble discovered another galaxy. Now we know that there are billions of galaxies in the universe.
