Another accomplishment NASA did is the discovery of water in one of the remote moons of the planet Saturn, called Enceladus.

What is the importance of Water discovery in Saturn anyway? This might mean that life exist at that moon. It was explained by By Daniel Engber on his article, “Why Do We Think Aliens Are Made of Water?” According to him,

What makes water so useful? First of all, it serves as a substrate for all the chemical reactions you need to make a living thing. To get something as complicated as biology, you’ve got to have a system that allows a wide variety of molecules to interact in a wide variety of ways. Water, which is a polar molecule—i.e., it has both positively and negatively-charged ends—acts as a “universal solvent.” That means it can dissolve many chemicals—including the organic compounds that are the building blocks of life on Earth—and allow them to recombine or attach to one another in various arrangements.

But according to the article written by Kenneth Chang, “Saturn Moon Has Geysers, Hinting Life Is a Possibility,”

Life requires at least three ingredients — water, heat and carbon-based molecules — and Enceladus may possess all three. As Cassini flew through the plumes of vapor and ice crystals rising into space from the eruptions, it also detected simple carbon-based molecules like methane and carbon dioxide, which suggest more complicated carbon molecules may lie on the moon’s surface.

So, if Enceladus has these three, then NASA can start to evacuate people from earth to that moon (kidding).
