Greenland scientists have discovered subglacial lakes trapped deep beneath the island’s massive ice sheet—some containing water that has not been exposed to sunlight for more than 100,000 years. These lakes remain liquid due to geothermal heat from below and immense pressure from the ice above. Researchers drill carefully through kilometers of ice to study the water and sediments, searching for clues about ancient climates and even microbial life adapted to extreme isolation. These environments
