People have looked at the night sky throughout history. In fact, ancient sailors used the stars as a tool. For example, Polaris, or the North Star, has historically been a useful compass because it is always in the northern sky. At first, people used their eyes to study the stars. Eventually, telescopes were invented. One famous astronomer, Galileo Galilei, made a telescope that was similar to the ones we use today. He used it to prove that Earth revolved around the sun. Astronomers since have made many discoveries with more powerful telescopes. What information can the reader gain from the text feature that is not discussed in the exerpt?
