On July 30, 1610, the famous astronomer Galileo Galilei became the first to observe rings around the planet Saturn. 

Shortly after the telescope was invented in 1608, Galileo peered out into the solar system and saw the amazing ring system. At first, he didn’t actually think they were rings.

Instead, Galileo thought Saturn might have planetary “love handles” that gave it a weird shape. He also wondered if perhaps he was looking at two very large moons on either side of the planet.

It wasn’t until 1659 that another astronomer named Christiaan Huygens figured out that these weird features were actually rings.
