A NASA study has discovered that Europa, one of Jupiter's moons, may be able to support life. This new study has found that the salty oceans of Europa can produce key elements for life, namely hydrogen and oxygen. The study also revealed that Earth and Europa actually have the same chemical composition and produce oxygen at the same rate relative to hydrogen. Scientists are planning to send a space craft to Europa by the year 2020 in order to learn even more about this moon.
