Or maybe not that bright - sounds like a brown dwarf (an almost-star that never quite got going - not ignited the way we'd normally think of a star but still a major heat source). I dunno if Jupiter's current mass is anywhere near that required for a brown dwarf? Maybe whoever it was either added more mass or forced the reaction somehow?

Wikipedia says the floor on a brown dwarf is about 12x Jupiter's mass, at least by today's definition; it's a slippery concept.

Still, getting Jupiter to cook a little warmer could create a little habitable zone around it even without its igniting like the Sun; warm enough, maybe, to melt Europa's ice shell and turn it into a water world.

-- Steve needs to consider that more, particularly in light of the rather nasty radiation bands close in to Jupiter.
