We know that each gas giant planet was warmest when it was young. This warmth came from internal heating from both radioactive decay and from gravitational potential energy. This warmth, in turn, means that the planet emits blackbody flux.

So this raises some interesting questions. Among them - how much of this early daytime flux affected the day-to-day temperatures of their moons?
