We know the moon and Mars do not have a magnetic field, so they are not suitable for permanent colonization. They may be just for temporary satellite locations. The closest planet we have found to colonize could be Europa, but we haven't visited there.
1) Mars has a magnetic field

2) The Moon has a magnetic field.

3) Europe isn't planet, it's a moon.
Also Europa has an ice crust, not good for living on at all.
What you're thinking of is that Europa might be one of the most likely places for life to exist. This would probably be sub-aquatic creatures, possibly very primative.
