NASA reveals new insights on 'Ocean Worlds' in Solar System

NASA has revealed new details from its missions exploring "ocean worlds" in the Solar System. NASA said that at least three moons of Jupiter: Europa, Ganymede, and Callisto possess vast oceans beneath their icy crust. Further, clouds containing hydrogen on Saturn's moon Enceladus showed it had nearly all ingredients for habitability. The missions aim to identify habitable worlds beyond Earth.
