Jupiter is easy to find because it is so bright. Only Venus and the moon are brighter in our night sky. Because it moves so slowly in earth's sky -- about one constellation of the zodiac eastward each year -- once you learn its location it is easy to find again.
Binoculars can reveal the four largest moons of Jupiter -- Io, Europa, Ganymede and Callisto. From one night to the next, it is possible to watch them change positions as they orbit Jupiter. In a telescope, Jupiter can be an awesome sight -- the bands in the atmosphere, the Great Red Spot and more.
