Question

Where on the web can I find where it shows what moon is where around jupiter on any night ?

Answer 1

Sky & Telescope has a Jupiter Moon page:

Chasing the Moons of Jupiter

You have to register, but it's free.

Some planetarium programs, like xephem, have features to show you where things are.  I run this under Linux, but it also works on Macs.

Answer 2

There is a javascript utility on the Sky & Telescope website at http://www.skyandtelescope.com/observing...

Answer 3

http://www.stellarium.org/

enjoy :)
