The news was posted by Yekaikin, who is currently taking part in a Vostok expedition.

Located deep in Antarctica where temperatures drop to minus 35-75 degrees Celsius, the Vostok Station is notorious for its extremely harsh research conditions.

In February 2012, Russian scientists reached sub-glacial Lake Vostok, which has lain untouched beneath the ice of Antarctica for millions of years.

Last week Vostok researchers brought up a sample of the lake's ice. It's hoped that samples from the lake will yield vital information about the origins of life.
