The volcano of Dallol in Northern Ethiopia is one of the most alien places on Earth, whose molten landscape surrounds the unearthly greens and bright yellow hydrothermal pools, considered some of the most extreme environments on our planet. Despite its beauty, the surroundings of the volcano are extremely dangerous for the existence of even those living organisms that have long and successfully been able to adapt to survive in super hot and swarkestone some places of our planet. According to the information portal livescience.org this fact can radically change the view of scientists about the possibility of existence of life on other planets, completely dashing the hopes of mankind for the acquisition of the “brothers on reason”.
Is there life on other planets?
In order to determine whether life can exist in one of the most extreme places of our planet, the researchers took samples from several pools of water located near the Dallol volcano. It is known that the local water bodies contain high salt concentrations differ from each other in the next important parameters, among which the most important are temperature, acidity and alkalinity. During the chemical analysis of water bodies revealed that some of them are filled with sodium chloride, while others contained a high concentration of salt based on magnesium, which is able to destroy the cell membrane of living organisms.
In such an extreme environment characterized by high acidity and salt content of magnesium, the researchers are unable to detect any traces of live microorganisms, which may indicate that the presence of the planet’s water in liquid form does not make it potentially habitable place. However, using electron microscopes, the researchers were able to detect the presence in water bodies of the so-called biomorphs, or mineral precipitation that mimic the tiny cell. Similar inanimate structures scientists might find on Mars, mistaking them for microfossils.
Despite such disappointing results, now scientists have isolated several planets, which can develop a hypothetical life. Most of all isepisode planet is Kepler-62e, whose index is the similarity to the Earth of is 0.83 to 1.00. Despite the fact that the planet has received such a high recognition, its large size and relatively low density make Kepler-62e is a fully water-covered world with a rocky bottom and average surface temperature approximately 17 degrees Celsius.
Despite the fact that the exoplanet was found a large quantity of water, the research of experts from the Spanish Centre of astrobiology regarding the availability of living near a volcano of Dallol in Ethiopia can disrupt the plans of scientists to find at least simple life in this remote from us at 1,200 light years the world.
Similar exoplanet may turn out to be Kepler-22b, whose Earth similarity index currently is 0.75. Located 620 light years from earth, Kepler-22b is a vast ocean with a small kernel in the center. On the possibility of existence of life in this large ocean a long time we had discussions, but in order to accept or refute the possibility of its existence, astronomers have yet to study the composition of its atmosphere with a telescope James Webb, whose launch into space scheduled in March 2021.
