How does the estimated volume of liquid water on Europa compare to Earth's oceans?
Answer
It is vast, potentially containing more water than all of Earth's oceans combined
The hidden saltwater ocean beneath Europa's icy shell is considered an almost unimaginable reservoir of potential. Scientific estimates suggest that this subsurface volume of liquid water is so massive that it could exceed the total combined volume of all the oceans currently existing on Earth. This immense scale underscores why Europa is such a key target in the search for extraterrestrial liquid water environments.
