Water vapour discovered on Saturn's moon

Huge plumes of water vapour and ice particles are bursting out from Saturn's moon Enceladus at supersonic speeds in a way that strongly suggests they come from liquid water down below the icy surface, scientists have said.

The research, published in the journal Nature, offers new evidence that the moon may harbor an underground ocean of water, meaning conditions might exist that could support life, even if only microbial organisms.

'We think liquid water is necessary for life and there is more evidence that there is liquid water there,' said lead researcher Candice Hansen of NASA's Jet Propulsion Laboratory in Pasadena, California.

'You also need energy, you need nutrients, you need organics. It looks like the pieces are there. Whether or not there's actually life, of course, we can't say.'
