Proxima b exoplanet may be habitable say scientists from the journal Astronomy & Astrophyics. The website Phys.org recalls that it was open in August of 2016 years and its characteristics are similar to Earth.
Scientists have created two climate models, one of which suggest the presence of similar to the earth’s atmosphere, and the other primitive atmosphere of nitrogen and carbon dioxide. Also take into account the dependence on the climate, length of day and year.
Modelling using the Met Office Unified Model, used to retrieve data about the climate of our home planet, indicates the presence on Proxima b liquid water and stable weather. Because of this, the chances of existence of life is quite high. However, to prove it or disprove it, you need more data and more calculations are sure of astrophysics.
