The uplifting air currents theory sounds like something unprobable for me. Since Europa (one of Jupiter's moons) is known to have an ice cape, and water is the origin for life, I trust more the theory that suggests that life forms have been traveling through our solar system in asteroids and other celestial bodies. This discovery increases the probability of there being some kind of life form in this moon, and it's definitely worth exploring (sendind a rover or something like that).<p>I'm so excited to finally know that we are not alone here, and it's even more exciting that it's something as close as the ISS! This can really take our understanting of the universe to the next level!
