Microbial discoveries in the Atacama Desert support life on Mars

Microbial findings in the Atacama Desert have implications for life beneath the surface of the planet Mars. The findings came from scientists at Cornell University and the Spanish Center de Astrobiology.

They announced the discovery of a fertile microorganism in the shallow soil layer of Chile. The layer in which the microbes get is full of clay content.

Thus, they received an indication of the presence of microbes. Starting with living microbes or microbes that have become fossilized.

Microbiological findings in the Atacama Desert

Launch from Earth to Earth if researchers make their findings. A layer rich in smectite, which lies about 30 cm or 11.8 inches below the surface of the core of the Atacama Hyper Drought.

They discovered a layer rich in wet clay. This phenomenon is rare and they have never seen it exist in this desert region before.

Soil moisture is relatively stable and high at about 78 percent, with all isolated under variable underwater conditions and very dry.

The study’s researchers talked about microbiological discoveries in the Atacama Desert. If the Atacama Desert has a smectite layer, there are 30 halophilic species. This species originates from the bacterium archea, which is metabolically active.

This was discovered for the habitat of microbial life that never existed before in the lower layers of the planet Earth.

“The findings of the microbiological groups vary in the smectite-rich underground layers of the Atacama hyperidm nucleus.” We have identified a collection of biological signatures in clay. This shows that shallow clay deposits are similar to those on Mars. “It may contain a biological signature and is readily available for this research,” said one researcher.

Findings on clay content

Meanwhile, our correspondent Alberto G. Fairen discovered that clay contained microorganisms. This is related to the discovery of microbes in the Atacama Desert.

“This discovery shows that there is something similar and it may have happened billions of years ago. In fact, this possibility still exists on the planet Mars. “If microbes still exist today, it is possible that new life on Mars still exists,” he said.

Researchers have discovered at least 30 species of microbes. Which, previously, they did not know about the existence of metabolically active bacteria and archaea (unique organisms).

This is quite significant given the very dry surface conditions. They also said that the shallow layers of Mars also contained microbes in the Atacama Desert or food debris.

With that, they can easily find them for future researchers. The soil conditions on the red planet are really very dry so far. However, the surface layer contains an abundance of clay in some areas.

Detection of soil condition with Curiosity

Then the findings of the microbes in the Atacama Desert can not only be detected by aircraft. The plane circled the space station.

But the findings on soil conditions, if detected through Spirit and Possibility (MER) and uriopopity. Although they do not complement the discovery with the species in the soil or the microbes that inhabit them.

Urioboptia also discovered various molecules that are organic and preserved inside ancient mud rocks. “Which can provide very important clues to the possibility of living in the past,” the researcher said of the report.

“This paper will help you lead the search. This is to inform where to look. “Then also about what tools we will use in the search for his side of life.”

Thus, scientists value microbiological discoveries in the Atacama Desert as information that helps them determine the best location on Mars. It is a search for evidence of microscopic life in the past. (R10 / HR via Internet)
