All these icy moons, including Europa
A Nasa spacecraft has detected oxygen around one of Saturn's icy moons, Dione. The discovery suggests oxygen may also be present in other places nearby more amenable to life.
Dione's sister moon, Enceladus is thought to harbour a liquid ocean below its icy surface. The same is thought to be true of Europa, Callisto and Ganymede which orbit Jupiter.
