Story highlights NASA will share insight about ocean worlds in our solar system on ThursdayResearchers believe that ocean worlds are good candidates for life beyond Earth(CNN) NASA will present new discoveries about the ocean worlds in our solar system on Thursday, the agency announced. Learning more about ocean worlds could help in the agency's quest for life beyond Earth. Earth is considered an ocean world because those bodies of water cover the majority of the planet's surface. Other ocean worlds in our solar system potentially include Jupiter's moons Europa, Ganymede and Callisto; Saturn's moons Enceladus, Mimas and Titan; Neptune's moon Triton; and the dwarf planet Pluto. It is believed that Venus and Mars were once ocean worlds, but the greenhouse gas effect and a vulnerable atmosphere, respectively, caused those planets to lose them.
