Life on Exoplanets: In a study funded by NASA, it was said that the chances of life are highest on the planets tilted on the axis like Earth.
Space agencies around the world, including the American Space Agency NASA, are engaged to search for others like Earth in the Universe. In such a situation, the question is emerging the most, which type of planet will have the most potential for life. At the same time, now the answer to this question is also being seen. According to a study funded by NASA, a star like Earth may have a higher chance of life on a planet tilted on its axis.
In the latest study, researchers prepared a model, in which the necessary conditions for life were maintained. During this, an attempt was made to understand the effect of the change in the situation on the amount of oxygen. Purdue University principal researcher Stephanie Olson said the model examined the effects of day length, atmospheric volume and terrestrial presence in aquatic life. He said, we were trying to understand what would be the effect on the organisms that produce oxygen.
How is oxygen produced on these planets?
Oxygen increases on a planet due to longer days, increased surface pressure and the formation of continents. According to the researchers, they also affect the movement of the ocean and the nutrients necessary for life. With their help, till date the amount of oxygen on earth has reached here. Similarly, when the angle of inclination of a planet on its axis was understood, it was found that it produces more oxygen in the oceans. In fact, it helps in better recycling of organic matter.
More than four thousand exoplanets discovered so far
Earth is tilted on its axis at 23.5 degrees and Mars at 25.2 degrees. On the other hand, Venus is tilted 177.3 degrees and Mercury is absolutely straight. The corners of the earth create better conditions for microorganisms to grow and larger organisms have a better chance of being born. This research was presented at the 2021 Goldschmidt geochemistry conference. Significantly, space agencies around the world are engaged in finding exoplanets like Earth. So far more than four thousand exoplanets have been discovered.
