Galileo used his hands. Unlike the Greeks who just wrote things down, Galileo made things. The refracting telescope along with other instruments were the offsprings of his innovation. Galileo discovered. While the rest the world believed in a world where the earth was the center, he believed in a heliocentric one. He distinguished planets from stars, by finding which ones moved (a confusing thought at the time). When observing Jupiter, Galileo noticed dim stars around the planet. He recorded this and checked again the next day. He noticed the position of the stars had changed. After recording the shocking results, he began to check everyday. At the end of a ten day period, he came to the conclusion that the stars were in fact moons with different sizes and orbits.
