For a planet that is favorable to the outward appearance of life, one of the most important requirements – between other geochemical, astrophysical and geophysical parameters – is that its orbit is in the habitable zone of one or another energy source, where the temperature Of liquid water. One of the most promising exoplanets is Next b, which revolves around Proxima Centauri, the closest star of the earth after the sun. And although at first it was speculated that the radiation was withered, a recent study suggested that can contain oceans and be suitable for life.
by means of mathematical models Similar to those used to analyze climate change on Earth, the researchers determined that Próxima b is capable of retaining large parts of liquid water on the surface, increase your chances of harboring living organisms enormously. The results of the study were published in Astrobiology.
Next Centauri. It is a small reddish star that belongs to the largest population of stars in the Milky Way: the red dwarfs. The distance to the sun is precisely determined by the parallax method: 4.24 light years.
Team estimates led by Antony of Genius, the NASA's Goddard Institute of Space Studies, pointed out that Proxima b is just enough to receive enough starlight and keep its surface above the freezing temperature of the water.
