The discovery of a microbial ecosystem deep beneath the Antarctic ice doesn't necessarily mean that life teems on frigid worlds throughout the solar system, researchers caution: subglacial Lake Whillans is not a closed system like Jupiter's moon Europa.
20 August 2014, 12:45 PM ET
Boring through ½ mile rock-hard Antarctic ice, researchers discover a completely isolated community of microorganisms living in Subglacial Lake Whillans. The finding could be an analog for subsurface life on Mars, Europa, Enceladus and other worlds.
