Not really - but scientists are encouraged that one of Saturn's moons may have the right stuff to support life.

According to the theory, Enceladus formed some 4.5 billion years ago by the mixing of ice and rock containing the radioactive isotopes aluminum and iron. Over a period of several million years, the rapid decay of the two radioactive elements produced a burst of heat that resulted in a rocky core enclosed by an ice sheet. Over time, the remaining decomposition in the core further warmed and melted the moon's interior.

If confirmed, the model suggests Enceladus possesses the necessary ingredients to support life -- a stable heat source, organic materials and liquid water.
