Who discovered Jupiter other than NASA?

Jupiter has been known since ancient times and was observed by various civilizations, including the Babylonians and Greeks. Galileo Galilei was the first to make detailed observations of Jupiter using a telescope in 1610, discovering its largest moons, known as the Galilean moons. Thus, while NASA has conducted extensive studies of Jupiter, its discovery predates the agency and is attributed to early astronomers like Galileo.
