Chemistry on Titan Could Lay the Groundwork for Life

Saturn's biggest moon, Titan, may possess the kind of chemistry that could eventually lead to life, albeit without water, a new study finds. Titan is larger than the planet Mercury, making it the biggest of the more than 60 known moons orbiting Saturn. Now, using computer models, a group of researchers has shown that a chemical on Titan's surface could lay the groundwork for the formation of life.
