Gather Images of Jupiter
Galileo looked at Jupiter through his telescope night after night drawing pictures of what he saw as the moons moved. Nearly 400 years later, we are able to take images through large telescopes and combine them to make one image. We will use this one image to track the path of the visible moons.
First we have to get the images we need. If you have enough time, you can request your own images of Jupiter.
You can find these and many more images of Jupiter's moons on the Explorations Pages link at the top of this activity.
