Earth bacteria THRIVE in lab simulation of Saturn moon's ocean, raising hopes of alien life

Scientists who recreated the subsurface ocean of Saturn's moon Enceladus in a laboratory discovered that deep-sea microbes did not merely endure the conditions — they thrived, even though those conditions had previously been regarded as too extreme for life. The team reproduced the near-zero oxygen, high dissolved carbon dioxide and strongly alkaline water believed to exist beneath Enceladus's frozen crust, then introduced bacteria drawn from deep-sea hydrothermal vents. Dr Nozair Khawaja of Freie Universitat Berlin called the result "a surprise" — the team had not expected to succeed.

The findings fall short of confirming life on Enceladus; what they demonstrate is that organisms with unusual metabolisms could theoretically survive there.

Enceladus spans roughly 310 miles and has surface temperatures of -201C, yet geothermal activity near its rocky core is believed to maintain a vast liquid ocean under the ice.
