  • Scientists thought that Lake Enigma in Antarctica was frozen from prime to backside. But, in 2019, they found that water existed 11 meters beneath the floor.

  • After extracting a pattern, a analysis crew led by the National Research Council of Italy found a set of assorted microbiota that’ve doubtless been separated from the remainder of the world for hundreds of years.

  • The scientists theorize that these microbes are the descendants of life that thrived within the lake earlier than its prime turned completely frozen.


In Jurassic Park, the Chaostician Ian Malcolm (portrayed by Jeff Goldblum) famously utters the phrase “life finds a manner.” While Malcolm’s cryptic warning applies to the fictional dinosaur island Isla Nublar, these phrases stay sage recommendation for biologists exploring the actual world as nicely.

Case in level: a brand new research led by the National Research Council of Italy found proof of life in a perennially frozen lake within the Antarctic. This is especially perplexing as a result of this lake—appropriately named “Lake Enigma”—was believed to have been frozen from prime to backside. But researchers found the presence of Pseudomonadota, Actinobacteriota, Bacteroidota, and very simple single-celled creatures within the superphylum Patescibacteria.

Patescibacteria is especially intriguing, as this organism is wholly absent from lakes studied within the McMurdo Dry Valleys. The outcomes of the research had been revealed within the journal Communications Earth & Environment.

The analysis crew traveled to the lake within the summers of 2019 and 2020, and with the assistance of ground-penetrating radar, found that Lake Enigma—true to its title—contained a secret: liquid water mendacity 11 meters beneath the floor. The researchers drilled into the ice, cautious to keep away from contaminating any water samples throughout extraction, and evaluation subsequently revealed a treasure trove of microbiota.

“Perennially ice-covered freshwater ecosystems are hotspots of biodiversity in Antarctica’s polar deserts, offering a year-round oasis for microbial life,” the authors wrote. “This research describes a novel instance of those ecosystems by including the huge freshwater Lake Enigma, one of many deepest hydrological formations in Victoria Land.”

The researchers theorize that the lake doubtless teamed with life earlier than its prime completely froze over way back, and that these microbes are the dwelling descendants of these historical life types. But this isn’t the one thriller surrounding this lake—resulting from its location, it ought to have dried up way back. But water nonetheless persists, suggesting its being fed by some at present unknown water supply.

Antarctica has lengthy served as an analog for the situations which are to be anticipated on different planets. The McMurdo Dry Valleys, for instance—which haven’t seen rain in almost two million years—are a pleasant environmental comparability for Mars, which can also be extraordinarily chilly and very dry (although Mars doesn’t a breathable ambiance). Finding life beneath a perennially frozen lake offers one other attention-grabbing information level for house missions just like the lately launched Europa Clipper, which goals to study if the water beneath the icy crust of Jupiter’s fourth largest moon comprises the situations to help life.
