Besides Earth, the solar system seems sterile. From the scorched plains of Mercury to the icy, frozen craters of Pluto, the solar system is dead. Lifeless. Or is it? Lurking underneath the barren deserts of Mars or the icy sheets of Europa, life could exist.
More and more evidence suggests that Earth may not be the only planet (or moon) with life in our galactic home.
Let's first take a look at the Jovian moon of Europa.
Very recently it was confirmed by NASA scientists that water vapor exists in the geysers spewing out from the moon's surface. This has huge implications about life on Europa, because water is one of the 3 key ingredients of life. The other 2, energy and complex chemistry, already likely exist from Jupiter's pull on Europa as well as volcanic vents, spurting out organic molecules.
