Researchers in Antarctica have revealed the discovery of a whole ecosystem living beneath the pack ice.
It seems a long time since scientists first started to drill down through the ice to sample the waters of one of Antarctica's many subglacial lakes, bodies of water that have remained completely isolated from the outside world as far as half a mile under the surface where by all rights nothing should be able to survive.
The thing is we know that there is life on Earth and it is so plentiful and so adaptable that it is hard NOT to find it. To put things into perspective, we also have life in deserts. There are plenty of deserts on Mars but life is not evident. It would be just as unexpected to find life on its polar caps.
