His telescope was small and showed blurry images, but Galileo was still determined to find things out in the sky. Galileo was able to find mountains and craters located on the moon with his telescope. Also, he found a ribbon of diffuse light arching across the sky which became known as our Milky Way Galaxy. Followed up by this, spectroscopes were made in the 19th century, allowing astronomers to gather information about celestial objects and chemicals. As technology advanced, astronomers discovered more and more about outer
