Scientists have applied a climate modeling system outside our planet

In 2019, NASA, after much debate, launched a simulation of climatic conditions on the planet Proxima Centauri b, the closest to us outside the solar system. The main difficulty was the lack of a coherent model - in the absence of any others, it was necessary to apply a modified version for the Earth. After months of work, NASA published the results of its work.

From reliable information: the star Proxima Centauri is smaller and colder than the Sun, but planet b is much closer to it, therefore it receives about the same amount of energy as the Earth. However, the Earth rotates, and that planet is held by tidal forces with one side to the star. The gravity there is probably three times lower than the earth, and the worst thing is that we can not look at the side turned to the star. But life, or rather, living conditions, can only be there.

Proxima Centauri b is a rather extreme planet, on one side of it there is eternal day and heat, and the other is covered with eternal darkness and ice. But this is an old version, and modeling has shown that under certain conditions, the circulating ocean can generate a huge amount of water vapor. Powerful winds carry it to the dark side, which may even be ice-free. But this equation with many unknowns - just add a couple of continents with high mountains, and the meteorological situation changes dramatically.

At the moment, after studying a series of models, NASA scientists are only sure that any of the scenarios presented can be on Proxima Centauri b, and a considerable part of them retain conditions for life on Earth's model.
