Scientists have found life in an Antarctic lake that was sealed off from the outside world by a thick sheet of ice several thousands of years ago.
Brine collected from boreholes drilled into Lake Vida contains scores of bacteria that clung on to life despite making their home in one of harshest
environments on Earth.The water in Lake Vida is acidic, starved of oxygen, and so salty that it remains liquid despite its temperature hovering around
the -13C mark all year round.
Microbial life has been discovered sealed in a brine lake beneath 65 feet of Antarctic ice after spending nearly 3,000 years isolated from
external energy sources.
The findings, detailed in the Proceedings of the National Academy of Sciences, describe the microbes’ Lake Vida habitat as aphotic (with little
or no light), anoxic (without oxygen), and slightly acidic brine with a temperature of -13C. Carbon dating has indicated that the
inhospitable-sounding brine has been isolated for more than 2,800 years.
Any Thought ?
Doesn't this discovery of microbes thriving in the salty, sub-zero conditions of an Antarctic lake raise the prospects for life on the Solar
System's icy moons ?
