Ocean worlds are a type of celestial body, typically a moon or planet, that harbors a significant amount of liquid water beneath its icy surface. These bodies are of particular interest to scientists and researchers because they are considered to be potential havens for extraterrestrial life. Ocean worlds in our own solar system include Europa, a moon of Jupiter, and Enceladus, a moon of Saturn. Scientists are actively studying these celestial bodies to better understand their potential for hosting microbial life and uncovering insights into the origins of life in the universe.
