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.
Galileo Gailei is the first person credited with using the telescope for astronomical observations. He did not invent the telescope. He is the first to have seen moons going around Jupiter, the rings of Saturn (though he incorrectly identified them), and that the Moon had cliffs and craters.
Saturn was the first planet discovered to have rings. They were first observed by Galileo Galilei in 1610 through his telescope.
Galileo Galilei found that there were spots on the sun and craters on the moon.

Venus is one of the planets that is visible without a telescope. The planet has been known since antiquity. Galileo was the first astronomer to study Venus through a telescope.
He was not the first astronomer; there were plenty before him going back to the Babylonians at least. Galileo, however, was the first to use a telescope.

Galileo Galilei (from italy)
The Italian astronomer Galileo Galilei was the first to observe that the moon had craters. He made this discovery in 1609 through his telescope.
Galileo did not discover Saturn. Saturn was known to people who lived thousands of years before Galileo. Galileo was the first person to see Saturn through a telescope, and the first to observe its rings. He made many of his observations from Venice.
