Is there life on Saturn's moon? Where there's water, there's a chance

At first glance, Saturn's moon Enceladus seems rather unremarkable: it is much smaller than the Earth's moon and is far away and completely covered in ice.

Yet beneath its frozen crust lies an ocean of liquid water, making it one of the most promising locations in the solar system in the search for extraterrestrial life.
