Jupiter and 4 of its moons on 9-28-09.

Jupiter is the largest planet and has 63 moons, but only 4 of them are easily visible from Earth. The 4 that can be seen with binoculars from Earth are: Io, Europa, Ganymede, and Callisto. In 1610 Galileo observed these moons and noted that they orbit Jupiter as does Earth's moon. He observed the movement of the moons and deducted that the Earth orbits the Sun the same way the moons orbit Jupiter. His highly controversial theory stated the Earth was not the center of the universe and was rejected by the Catholic church, he was forced to retract his statements. Hmm, it sounds a bit like the evolution controversy! :)
This is the best planet photo I have been able to get so far. I took it with my spotting scope.
