A new study has revealed that the closest potentially habitable planet to our solar system, Proxima Centauri b, could have liquid water. This supports previous studies which claimed that Proxima Centauri b is likely to have water and can support life.
In this newest study, a team of researchers led by Ian A. Boutle from the Met Office UK created a simulation of the climate of Proxima b using the Met Office Unified Model. In the simulation, the atmosphere of the planet was designed to be like that of the Earth. However, small changes were made. The simulated Proxima b atmosphere was mainly made up of nitrogen and contained small traces of carbon dioxide. The researchers also looked at how the atmosphere of the planet could be affected by its unique orbit.
In the end, the model atmosphere of Proxima b created by the scientists confirmed simulations from previous studies. The researchers concluded that the planet could be habitable and that its surface temperature could be conducive to the existence of liquid water. This study has been published in the Astronomy and Astrophysics journal.
