About the graphic:
When Galileo turned his telescope on Jupiter, he
discovered that it has four moons which revolve around it.
From this he inferred that the Earth and the other
planets could revolve around the Sun. This was one of the
key discoveries which started an
intellectual revolution which resonates to this day.
