Sometimes it is felt that there are no hidden secrets on this planet earth. However, scientists have come across a surprising discovery into the depth of ice sheets of Antarctica – another largest lake of this world. Vostok station had been established by the Russians in the year 1957 and post 20 years, the satellites found out this largest lake beneath the Vostok base which is 10,000 sq.km same as Lake Ontario but is twice in depth. Scientists are very much eager to know about this lake as it might shelter unique fauna and flora. Contrarily NASA is excited to know – what this lake can teach people concerning extraterrestrial life.
