objects in the solar system discovered through the use
of the telescope. Their proven existence played a
central role in Galileo’s famous argument in support
( 5 ) of the Copernican model of the solar system, in which
the planets are described as revolving around the Sun.
For several hundred years after their discovery by
Galileo in 1610, scientific understanding of these
moons increased fairly slowly. Observers on Earth
( 10 )succeeded in measuring their approximate diameters,
their relative densities, and eventually some of their
light-reflecting characteristics. But it was the
spectacular series of photographs sent back by the
