US researchers come to the sudden conclusion that the Earth is not the best planet for life

American researchers have come to the surprising conclusion that the Earth may not have been the best planet for life, with exoplanets orbiting distant stars capable of leading a more diverse life, using NASA's climate model to explore the most likely exoplanets. Shaped to polarize life – outside our solar system.

Planets with denser atmospheres and lower rotational speeds can contain water more efficiently, creating a potential host environment for extraterrestrial life and the results can help center the planet. future of the search for life on other worlds.

Geochemist Stephanie Olson and her colleagues at the University of Chicago have used the programs developed by NASA to model the potential conditions of different types of exoplanets, particularly climates and potential habitats for the oceans.

"NASA's quest for life in the universe is focused on the so-called planets of the habitable zone, worlds with the potential for oceans of liquid waters." But not all oceans are not as hospitable – and some oceans will be better to live than others, because of global business models. "

The researchers were able to use their models to identify the types of planets that can develop and maintain a variety of lives.

"We used an ocean circulation model to determine which planets would have the most efficient vapors, and thus provide particularly hospitable oceans," said Olson.

Climbing in the Earth's oceans restores the nutrients from dark depths to areas exposed to more sunlight in the seas. Thus, more exposure to light means the availability of essential nutrients, increasing the biological activity.

"These are the conditions we need to look for exoplanets," said Olson.

In this sense, the researchers concluded that the Earth may not have been the perfect planet for life and that there were more hospitable worlds that could be elsewhere in the universe.

For the moment, no powerful telescope has been developed to identify appropriate exoplanets and test researchers' conclusions – but Olson hopes this will change soon.
