Galileo Galilei (1564-1642), first to devise and use a telescope for astronomical observations, discovered the moons of Jupiter, and the motion of sunspots across the solar disc - sign of a less than perfect sun, which also rotated! His many observations confirmed the Copernican theory of the motion of earth and planets around the sun, and brought him in conflict with the Inquisition; for such heresy he spent his last years under house arrest. Here he is honored on Italian and Czech stamps: eppur si muove!
