Is there life on Titan? If so, it’s very rare

View larger. | This artist’s illustration depicts Titan’s organic-rich surface, with a lake near the north pole. Hydrocarbons coat the icy surface, hang in the atmosphere as smog and are the liquids in the seas and lakes. So, could there be life on Titan? A new study suggests it would most likely be in the subsurface ocean below and be limited to only a few pounds of microbes for the entire moon. Image via NASA/ JPL-Caltech/ NASA Photojournal.
