Mountains on the Moon
Galileo demonstrated the existence of mountains on the Moon (Figure 1) . Some Aristotelian physicists taught that the shading of the Moon was internal, its surface as smooth as a marble.
Galileo inferred the existence of a lunar atmosphere from the fact that the mountains are not seen on the edge of the lunar disk.
