Actually, Galileo wasn't the person who discovered that the earth was a sphere.
People had known the earth was not flat for centuries before Galileo's birth - much navigational technology had all based on that fact, and would not have worked otherwise. Galileo is more well known for providing observations and evidence that the sun, not the Earth, was the centre of the solar system - however the main proponent of this fact was Copernicus, a century previously.
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!
