CN ) - Scientists have found a possible explanation for the reasons why NASA , ESA and many other space agencies believe that there must be life on planets.
When we face the climate disaster brought by global warming ; on another planet, when the earth becomes too cold to survive, the entire organism may have died, which is also due to climate change.
It is also a planet in the solar system, and is neatly located in the "region" lives "Blonde Girl, and is also a rocky planet like Earth: Mars .
This research, just published in Natural Astronomy, not only confirms the hypothesis that there is life on Mars that space agencies and many researchers around the world believe, but also explains how this life was formed and is invisible to us.
As some previous studies have shown that just after Earth, Mars was nearly 40 Life began to exist billions of years ago. Their protozoa are microorganisms like our planet, but are a group of organisms that feed on hydrogen (a powerful greenhouse gas) and emit methane (also a greenhouse gas, but not as powerful as hydrogen).
Scientists simulated how life was born and developed on Mars based on the data from Mars rover Curiosity, the "warrior" who helped NASA discover traces of methane and the first components of life. Scientists reconstructed the history of ancient Mars.
They found that life may not be able to sustain itself in all the favorable environments that helped it emerge, but it can easily destroy itself by destroying the basis on which it relies on.
"The components of life are everywhere in the universe. So life may appear frequently, but it cannot maintain habitable conditions on the surface of the earth, which makes it great. "The tension is fast. Our experiments show that even biosphere can have a complete self-destruct effect," - astrophysicist Boris Sauterey from the Higher Normal University in Paris, France confirmed to Space.
summarizes the study, Science Alert says the work can explain that since Mars is farther from the sun than Earth, life exists, it requires a layer of greenhouse gas that is thick enough and strong enough to keep warm, in this case hydrogen.
But when life evolved into a real biosphere, constantly consuming hydrogen and replacing methane, the earth's endothermic layer is no longer strong enough, causing the temperature to rise by 10-20 degrees Celsius to drop to minus 57 degrees Celsius.
This is a global climate disaster that makes the earth's surface undoubtedly a dead world.
These microorganisms have managed to dig holes underground, reaching a kilometer deep in search of a warmer environment. Can hold on for a while. The possibility that they still exist is slim, but a silver lining is the traces of methane currently found by Curiosity. Methane is likely to be a byproduct released from life.
