This question already has an answer here:
Humanity is about to leave our solar system for some reason and a gas giant with 60 moons has been spotted in the Goldilocks zone of a nearby solar system. They arrive there and it turns out, a space-fairing community has already developed.
Firstly, could a Jupiter-like planet form in the Goldilocks zone? Secondly, could a few of its moons be able to support life? Thirdly, could advanced, space-faring life evolve separately on at least 4 of the moons? Fourthly, would they be friendly to our earthlings? And finally, what might society and culture be like?
