Scientists just found even more evidence that Europa - one of Jupiter's 67 known moons - might host alien life deep within its icy oceans. The little moon has long been labelled by NASA as "", thanks to the deep, salty oceans that are strongly suspected to be hidden beneath its frozen crust. And now a new study has shown that the chemical balance of those oceans would be very similar to the ones here on Earth, suggesting there'd be enough hydrogen and oxygen there for life to form - even without volcanic activity. http://www.sciencealert.com/nasa-just-found-even-more-evidence-that-europa-could-host-alien-life
