Ask an Astrobiologist
"What would planet earth look like without any water? What planet in out solar system would best describe earth without water?"
  1. Question

    is there really bacteria in the water on one of saturn's moons?

    Not that we know of. Scientists have no way to search for life on any of the moons of Saturn, bacteria or otherwise. Any suggestion of life on any of the outer-planet moons is speculation. David Morrison
