Planet Earth has a presence in extreme environmental areas like deserts or frozen tundras. However, the land has some parts where life cannot exist. According to a new study, scientists discovered a city in Ethiopia where life cannot live. After conducting multiple tests, scientists could not even find the microorganism in Dallol pools. Dallol is a scorching, salty, and acidic place on the earth.
Moreover, its ponds extend across a volcanic crater. A daytime temperature of Dallol can go up to 113 degrees Fahrenheit even in winter. Furthermore, the place has hyper acidic pools with negative ph value.
Lopez Garcia, one of the researchers, said, “After analyzing more samples than the previous study, we found no life on this part of the earth.” However, they found a diversity of salt-loving microorganisms outside the pond. Researchers tried to classify these organisms bases on genetic markers. They performed chemical analysis and electron microscopy for the study. Sometimes minerals rich in silica may mimic microbial cells. However, scientists could show the difference between silica and microbial. Scientists used evidence of life in extreme environmental conditions on earth for this study. Researchers said, just because the area has liquid water, does not mean there is life present.
Lopez Garcia said, “We have found evidence that there are places on earth like Dallol pools that are sterile even though they contain liquid water.” Dallol ponds have chemical barriers like chaotropic magnesium salts that break down oxygen. Life receives no encouragement in the pools having salt and hot acidic environment. According to Lopez Garcia, “We would not find any life forms in similar environments on other planets, at least not based on biochemistry similar to terrestrial biochemistry.” Researchers will continue to study the pools to find out more about the limitations of life. There could be more places on earth with no living organisms.
