While scientists have not found life on Enceladus, Saturn's moon, they have found the next best thing: food that could sustain potential life. The food source is in the form of molecular hydrogen, which could feed microbes as it does here on Earth.

Scientists detected the molecular hydrogen in plumes of water vapour erupting from beneath the moon's icy surface, a critical ingredient in a process known as methanogenesis. On Earth, this provides food and energy to microbes deep in the oceans.

And the only plausible source, they concluded, are hydrothermal reactions between hot rocks and the water in the moon's ocean.
