Ring around the Planet
Galileo first discovered the rings that circle the butterscotch-colored planet known as Saturn in 1610. Using one the first telescopes ever made, Galileo assumed that Saturn's rings were attached to the planet and described them as handles. Forty-five years later, Dutch astronomer Christiaan Huygens correctly noticed that Saturn's rings surround the planet, but are not attached to it. The rings were named as they were discovered and were named after letters of the alphabet.
