Jupiter’s moon Europa is often thought of as possible abode for life, because of the potential liquid water ocean beneath its icy surface. Europa has been speculated to be one of the most likely locations in the solar system for potential habitability. Life could exist under the ocean.
Scientists have researched the salt from a subsurface ocean may likely contain geological features on Europa, and this suggests that the ocean is interacting with the seafloor, which might be important in determining if Europa could be habitable.
