Moon meets Jupiter on Dec. 4, 2004: The moon and the dazzling planet Jupiter will cross paths several times in 2013, but the most spectacular meeting will occur Jan. 21. Even a pair of binoculars should reveal Jupiter’s two largest moons, Ganymede and Callisto, just off the moon’s shadowed horizon, as seen in this image from 2004.
