17 Known Exoplanets Could Have Oceans of Liquid Water

Astrobiologists believe that the Solar System's ice worlds are some of the most interesting places to search for life. These are moons or dwarf planets with thick ice shells surrounding oceans of liquid water - the perfect habitats for life. A new NASA study has found 17 exoplanets that have the right size, density and distance from their stars, and are probably similar to Europa or Enceladus and might even have geysers blasting water into space.

The search for life is tied to the search for liquid water. That’s why astronomers are so keen on detecting rocky, Earth-like exoplanets in their stars’ habitable zones. In a habitable zone, a planet receives enough energy from its star to maintain liquid water on its surface, given the right atmospheric conditions.

But in our Solar System, we’ve found worlds with liquid water that are way beyond the habitable zone. Can we do the same in other solar systems?
