Jupiter and three of it's sixty-three companions, the Galilean satellites Europa, Ganymede, and Callisto in order of increasing distance from Jupiter. The fourth Galilean satellite, Io, is behind the planet. 

2009 has been designated as the International Year of Astronomy in celebration of the 400th anniversary of Galileo's use of a telescope to study the heavens.

@ Dandudin: I used a Canon 20D camera (since deceased*) and a Canon 100 -400 IS L lens, with a Tamron 1.4x teleconverter on a fixed tripod.

The moons are approximately fourth magnitude, which means if Jupiter wasn't there drowning them out they would be naked eye objects. In fact some people with extremely good vision (usually smart aleck kids) can actually see them without optical aid.

* The camera and lens were on the tripod and were knocked over by yours truly. The lens survived but the camera was non-functional. Fortunately I had a 300D as my backup body.
