Scientists have developed a new theory about life on Mars and the planet’s habitability through a model they have developed. The theory is that ancient microbes caused a climate crisis on the planet and prevented advanced life from forming on the planet.
A new theory has been put forward about Mars, which is one of the structures thought to be suitable for life in the Solar System. Scientists, in their article published in the journal Nature, ancient microbial life claimed to cause climate change.
Scientists have these theories 3.7 billion years ago He produced it through a model that simulates microbes living on Mars that consume hydrogen and produce methane. At that time, the atmospheric conditions of Mars were the same as the Earth of that day.
But Martian microbes took a different path from Earth microbes:
ancient microbial life on Earth, preparing the conditions necessary for today’s living things played a big role. Microbes have created an environment to help them thrive. But according to the simulation, the situation was different for microbes on Mars: It’s just at the beginning of the road. they made their own ending.
According to the model, this is due to the gas composition of the two planets and their distance from the Sun. Mars, which is farther from the Sun than Earth, maintains temperatures suitable for life. carbon dioxide and hydrogen dependent on heat-trapping greenhouse gases such as
Ancient microbes on Mars also consumed hydrogen, a powerful greenhouse gas, and produced methane. So microbes slowly heat trap blanket they consumed the layer that served as Eventually, Mars became so cold that advanced life forms could not form.
When the Martian surface temperature drops from the tolerable 10 to 20 degrees Celsius to -57 degrees, microbes began to flee deeper into the planet. So much so that within hundreds of millions of years, microbes had descended to 1 kilometer below the surface of the planet.
The new theory of scientists is currently without proof case. NASA’s Curiosity spacecraft has previously found traces that could be proof that microbes still exist on Mars. However, traces of methane gas have also been found by satellites in the Martian atmosphere. To prove the theory, it is necessary to find out whether any of these ancient microbes survived.
Fossils or living specimens of ancient microbes can be found in the low-mid latitude plains of Mars, according to scientists.
