extraterrestrial ocean

An extraterrestrial ocean refers to a large, liquid water body that exists beneath the surface of a celestial body outside Earth, such as a moon or planet. These oceans are hidden beneath thick ice layers or other surfaces, maintained in liquid form by internal heat or gravitational forces. They are significant because they could harbor conditions suitable for life beyond Earth. Notable examples include the subsurface oceans thought to exist on moons like Europa (Jupiter's moon) and Enceladus (Saturn's moon). Studying these oceans helps scientists explore the possibility of extraterrestrial life and understand the universe's diversity.
