Our solar system is filled with moons that defy imagination. One moon boasts a vast internal ocean, possibly harboring the ingredients for life. Another is a volcanic nightmare, constantly spewing sulfurous plumes that paint its surface in yellows and reds. There's even a moon with a bizarre, two-toned appearance, with one side reflecting sunlight while the other remains cloaked in darkness. These are just a few of the fascinating celestial bodies orbiting our gas giants and dwarf planets, each holding the potential to unlock incredible secrets about our universe.
