Galileo galilae
I"m thinking Galaleio
Galileo was probably the first to study Jupiter in detail, with his telescope.
Galileo made many wonderful contributions to science. He was the first to mount a lens in a telescope and he was also the first to discover that Jupiter has moons (to be precise, he spotted the four largest moons of Jupiter).
The telescope, invented by Galileo in the early 1600's, allowed us to see objects better that were far away. Galileo is credited with using his first telescope to discover Jupiter's moons, Saturn's rings, and the craters and other features of our moon.

Galileo was the first to look at the planet Jupiter through a telescope, and to observe the moons of Jupiter (the 4 largest moons are still known as the Galilean moons).
He Discovered The Jovian Planets ,i.e., jupiter, saturn, neptune and uranus
The moons of Jupiter.
The first person to discover one of Jupiter's moons was Italian astronomer Galileo. Galileo invented a telescope and was able to modify it to see celestial bodies more clearly than is possible with the naked eye. This discovery occurred between 1609 and 1610.

Galileo discovered Jupiter's four largest moons, including Io, Europa, Ganymede, and Callisto, in 1610. He observed them using a telescope, marking the first time celestial bodies were discovered that did not orbit Earth.
