Galileo's paper on Jupiter's moons. Sketches of the changing position of the moons of Jupiter over the course of 12 days, as recorded by the Italian physicist, mathematician and astronomer Galileo Galilei (1564-1642). The text is in Latin. Jupiter is the large circle, while the four moons are the dots either side. Galileo's discovery of these moons was made in 1610, using telescopes he had built himself. This was the first time it had been shown that heavenly objects existed that did not orbit the Earth. This challenged existing views that held the Earth to be at the centre of the universe. The moons are named the Galilean satellites in Galileo's honour. These sketches were published in Istoria e Dimonstrazione (1613).
