Exoplanets, worlds beyond our own Solar System, are a wild bunch: some are gas giants like Jupiter, but are scorching hot due to orbiting closer to their star than Mercury does the Sun, some are frozen hulks, while others may be water worlds covered entirely by ocean, and still others may sport clouds and rain of liquid gemstones.
