Recent simulations suggest that the ancient atmosphere of Marte might have provided a continuous supply of formaldehyde, which would have potentially led to the creation of various organic compounds.
The organic materials discovered in Marte may have originated from formaldehyde atmospheric, according to a new hypothesis regarding the possibility of past life on the red planet.
Scientists at Tohoku University, Japan, have investigated whether the early atmospheric conditions of Marte They had the potential to promote the formation of biomolecules, organic compounds essential for biological processes. The findings of him, published in Scientific Reportsoffer intriguing information regarding the likelihood that Marte harbored life in its distant past, according to the authors.
Nowadays, Marte It presents a hostile environment characterized by dryness and extreme cold, but geological evidence suggests a more hospitable past. About 3.8 to 3.6 billion years ago, the planet probably had a temperate climate, sustained by the warming properties of gases such as hydrogen. In such an environment, Marte it might have had liquid water, a key ingredient for life as we know it.
The researchers investigated whether the formaldehyde might have formed in the primitive environment of Marte. He formaldehyde It is a simple organic compound that plays a crucial role as a precursor for the formation of vital biomolecules through purely chemical or physical processes. These biomolecules, such as amino acids and sugars, serve as building blocks for proteins and RNA, essential components of life.
Valuable clues regarding the possibility of past life
Using an advanced computer model, the team simulated the possible atmospheric composition of the Marte primitive to explore the production potential of formaldehyde. The model was built based on the assumption that the atmosphere was rich in carbon dioxide, hydrogen and carbon monoxide.
Their simulations suggest that the ancient Martian atmosphere might have provided a continuous supply of formaldehyde which would have potentially led to the creation of various organic compounds. This raises the intriguing possibility that organic materials detected on the Martian surface might have originated from atmospheric sources, particularly during the planet’s first two geological periods.
“Our research provides crucial information regarding the chemical processes that may have occurred in the ancient Marteoffering valuable clues regarding the possibility of past life on the planet,” says Shungo Koyama, lead author of the study, in a statement. By revealing that favorable conditions existed for the formation of biomolecules, the research expands our understanding of the planet’s ancient capacity to sustain life.
Next, the team plans to analyze geological data collected by NASA’s Mars rovers, with the goal of increasing their understanding of the organic materials present early in the planet’s history. By comparing the carbon isotopes expected from ancient formaldehyde With data from Martian samples, they hope to get a better picture of the processes that shaped the planet’s organic chemistry.
