In the early 17th century
Galileo did not discover that the Earth is a sphere; this fact was already known by ancient Greek astronomers. However, Galileo's observations through his telescope, including the phases of Venus and the moons of Jupiter, provided further evidence to support the heliocentric model of the solar system proposed by Copernicus, which implied that Earth was also a sphere.
He did not need to discover that as it was already known by the ancient Greeks.
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.
Heliocentrism is the "truth" discovered by Galileo that is depicted burning in the fire with him. Heliocentrism is the idea that Earth and the other planets in our galaxy revolve around the Sun. The fire in the picture represents the sun, with the surrounding people representing the planets and the Earth's moon. Hope this helped!
