Saturn's Moon Enceladus Could Support Underwater Life


Saturn's moon Enceladus is proving to be more interesting than Saturn itself. NASA researchers have followed a series of 'breadcrumbs' back to the moon which suggest there would be life living underwater.

Researchers recently discovered some tiny grains of silica within the Saturn system. It transpires that these grains are -- as far as we know -- only caused when 'slightly alkaline, slightly salty water that is super-saturated with silica undergoes a big drop in temperature.'

Rather conveniently Enceladus is an enormous floating rock of hydrothermal activity and this combined with the moon's porous core has led researchers to conclude that underneath its ice-covered surface could be a 6-mile deep ocean rich in minerals.

This hydrothermal activity on Earth has long been considered the perfect cradle for life to form leading some to suggest that a similar process could be taking place on Enceladus.
