"So you've got subsurface liquid water, simple organics
and water vapor welling up from below. Over time -- and
Enceladus has been around 4.5 billion years, just like Earth
and the rest of the solar system -- heating a cocktail of simple organics,
water and nitrogen could form some of the most basic building
blocks of life," Brown said. "Whether that's happened at Enceladus
is not clear, but Enceladus, much like Jupiter's moon Europa and
the planet Mars, now has to be a place where we eventually search for life."
