Between 2016 and 2018, samples taken from four zones within the Dallol geothermal complex were studied by researchers. The region is found in Ethiopia.

Scientists from France say that they have discovered a place where no life exists. The only thing that exists is water in the area.

These findings were made while visiting the “inhospitable” Dallol hydrothermal pools of north Ethiopia near the Eritrean border. The findings were published by the Journal Nature Ecology & Evolution, the Diversity Ecology and Evolution of Microbes (DEEM) team of biologists from French national research agency CNRS and the University of Paris-Sud.

The researchers claimed “We identify two major physicochemical barriers that prevent life from thriving in the presence of liquid water on Earth and, potentially, elsewhere, despite the presence of liquid water at the surface of a planet being a widely accepted criterion for habitability”.

Many scientific techniques were deployed in 2016 and 2018 trying to search for any trace of life in the Dallol ponds and lake systems. The conclusion was that the extreme combination of saline and acid present were to much for any organism to survive. The researchers also found large amounts of magnesium in the water.

This helps to confirm a theory that the water can not contain any harmful substances or bacteria because living cells are destroyed in these conditions.

In an earlier study, evidence of tiny microbial life was claimed to have been found surviving against all odds. Hope is expressed by the researchers that the findings will serve as a warning about how scientists should interpret bio-signatures on earth and in space. They also hope it will add to restricting the presumed parameters for habitability.
