core plexus writes "Plans to drill deep beneath the frozen wastes of the Antarctic, to investigate subglacial lakes where ancient life is thought to exist, may have to be reviewed following a discovery by a British team. In a Letter to Nature they report that rivers the size of the Thames have been discovered which are moving water hundreds of miles under the ice. The finding challenges the widely held assumption that the lakes evolved in isolated conditions for several millions years and thus may support microbial life that has evolved 'independently'. It has been suggested that if microbes exist in the lakes, they could function in the same way as those in the subsurface ocean of Jupiter's moon Europa or within subsurface water pockets on Mars."
