Which thinker from the Scientific Revolution was the first to observe Jupiter's moons

1 answer

The thinker from the Scientific Revolution who was the first to observe Jupiter's moons was Galileo Galilei. He made this observation in 1610 using a telescope he had improved. His discovery of the four largest moons of Jupiter—Io, Europa, Ganymede, and Callisto, now known as the Galilean moons—provided significant support for the Copernican heliocentric model of the solar system, challenging the geocentric view that had dominated prior to the Scientific Revolution.
