Europa is one of Jupiter's larger moons. It appears to have a thick layer of ice on the surface, and some scientists believe there may be oceans
underneath. These oceans, if indeed they exist, could perhaps support life. Fossils have not been found there, as no probe or craft has actually
landed on Europa. I think NASA plan to do this however. It's an interesting subject, as ( assuming they are not already here ) Europa is one of the
most likely places in the solar system where we might find life
yes, europa is good, but as I explained in another board, people living there for a long time, would never be able to return to earth, their hearts
would be too weak...
another possibility is Titan, a moon of Saturn, there is N and CO2, thus theoretically we can grow plants there which would produce O2 for us to
breath! Plus there is a lovely view!
