Exploratour - Life in the Solar System
Like other icy moons, Europa is small, with no air to breathe, with direct exposure to space and the charged particle environment of Jupiter's magnetosphere. On the surface, the temperature is very very cold.
Nevertheless, the interior of Europa may have been warm enough at one time to contain a liquid layer just under the surface. On Earth, we know that there are some creatures which can survive in an environment of very cold water, such as under the ice of the north pole.
This means that, if the conditions are just right, there may be living creatures on Europa under the icy surface! Read more about this possibility be taking the Exploratour Does Euorpa have an Ocean?
