Obviously, that makes me think of...
It is pretty interesting to see the researchers make statements like: "Our results demonstrate that the potential for habitable conditions is not necessarily restricted to Earth-like rocky exoplanets." If you're so inclined, you can find the original paper here.
Of course, we live on a pretty watery world ourselves...and a paper has just come out supporting the idea that at one point, our homeworld may have been completely (or almost completely) covered by ocean. Once again, ScienceAlert has a nice article focusing on that aspect of the work.
If you'd like to see more about ocean worlds, NASA has a nice page about them. (Did you know that most of our ocean water may have come from asteroids? I didn't...)
