Lake Vostok is the largest of Antarctica’s almost 400 known subglacial lakes, located beneath Russia’s work station of the same name in East Antarctica. In January 2015, Russian scientists drilled a borehole into the ice, obtaining a sample of freshwater untouched for millions of years. YouTube channel Riddle detailed the exact task they took to expose forms of life never seen before on Earth.
The documentary detailed last month: “When scientists decided to look under the ice of Antarctica, what they saw surprised not only ordinary people, but also the researchers themselves.
“It turns out, that under the ice of Antarctica there’s a whole lake, and it’s also quite large, about 5,800 square miles.
“The depth of the reservoir reaches about 1,200 metres.
“Since this reservoir was discovered near the Russian polar station Vostok, the lake was also given the same name.”
The series continued, explaining how organisms lived in the toughest of conditions.
It added: “This giant pond is hidden under a huge layer of ice, with a thickness of 11,886 feet, or 3,623 metres.
“For this reason, the researchers did not expect to find even the smallest signs of life, in such harsh conditions, the temperature reaches -89C and the ice pressure exceeds the pressure of the moons of Jupiter and sunlight never breaks through.
“Few organisms living on Earth can survive in such an adverse environment, however, scientists still managed to find life in such extreme conditions.
“At the time, it was completely unlike anything they had ever seen before, researchers discovered a new type of bacteria, that was given the name W123-10, the DNA of this is only 86 percent identical to other living things on planet Earth.”

However, this discovery was not just useful for understanding Earth.
It may mean that life on Mars is hiding below the surface too.
The series concluded: “The reason was because the ice was isolated from the rest of the world for several millions of years, so the bacteria found there developed over separately from all living organisms on our planet.
“There were traces of around 3,500 species of living organisms living in the lake, which has led researchers to a very important hypothesis.
