Javascript Jupiter

Here are the four bright "Galilean" moons of Jupiter -- Io, Europa, Ganymede and Callisto -- and their shadows. It also shows the approximate position of Jupiter's "great red spot" (GRS).

This is an experiment on doing graphics in HTML/CSS/Javascript, re-implementing my Java Jupiter page without Java.

Miguel Moreto has adapted this code for a neat mobile phone app called Mobile Jupiter.
