Oceans help make life on Earth possible. So if there are oceans beyond Earth, do living things exist on those worlds, too? This is a question that NASA scientists are trying to answer. Right now, we know there are moons and dwarf planets in our solar system where oceans do exist. And there are more places where they could exist. To find out more, we will need to send spacecraft to study these places up close. But we already have some good clues to get us started.
Flip through the slideshow to see what we know about ocean worlds in our solar system. Which of these places do you think is most likely to have living things?
