Scientists have yet to find traces of life on Mars. But the new survey data has led them to believe more and more that, at least in the past billions of years, there must have been microbes living on this red planet. But they may have self-destructive behavior that will eventually die out.
A study published Oct.10 in the journal Nature Astronomy suggests there was a high probability that 3.7 billion years ago Mars had microbes that consumed hydrogen and excreted methane. during the same period The world has already given birth to the same life.
A computer model was created. to predict the effect Martian microbes will have on their planetary environment. It turned out that if microorganisms ingested hydrogen it really existed. They will have a very negative effect on the atmosphere and their livelihoods. This is different from the effects of this microorganism on the planet.
Because the atmosphere of Mars is mainly composed of carbon dioxide and hydrogen. They are both greenhouse gases that help trap heat from the sun. Make Mars, which is farther from the Sun than from Earth. It was warm enough to give life to life about 4 billion years ago.

However, computer modeling indicates that if microorganisms that eat hydrogen and excrete methane existed at the beginning of Mars They quickly deplete hydrogen in the atmosphere. until Mars loses its ability to store heat and the star’s surface has cooled to the point that life can no longer be inhabited.
The model’s predictions indicate that the surface temperature of Mars, where the atmosphere is covered, is low. It dropped from the original range of 10-20 degrees Celsius to the coldest point at -57 degrees Celsius, causing the microorganisms responsible for climate change. It may have escaped the cold in the rock layer up to 1 kilometer from the surface before becoming extinct about 200-300 million years later.
within the next decade, humans may have the opportunity to set foot on Mars and explore the traces of ancient life on their own. This will demonstrate whether the above assumptions are true or not; however, traces of methane have been found on Mars. which is believed to be caused by living things
Dr Boris Soterey, lead researcher at the French Institute of IBENS, concluded: “The elements that give life to life can be found everywhere in the universe. Therefore, it is possible that life is constantly born in the stars. But if an organism does not is able to maintain an environment conducive to life will quickly die out ”.
