Who first observed Saturn and when did he do it?

Saturn was first observed through a telescope by the Italian astronomer Galileo Galilei in 1610. While he noted the planet's distinctive rings, he was unable to clearly identify them as rings due to the limitations of his telescope. Galileo's observations marked a significant advancement in the study of the solar system. Subsequent astronomers, such as Christiaan Huygens, later clarified and detailed the nature of Saturn's rings.
