Hidden beneath Antarctica’s icy surface are more than 400 subglacial lakes, including the vast Lake Vostok. These bodies of water remain liquid, despite frigid temperatures, thanks to geothermal heat and the immense pressure from the ice above. In total darkness and isolation, these lakes harbor microbial lifeforms that have adapted to survive in such extreme conditions. Studying these unique oases not only expands our understanding of life on Earth but also guides the search for extraterrestrial organisms in environments like Europa or Enceladus.
