Proxima Centauri- A new planet has atmosphere to support Alien’s Life. An ‘Earth-like’ planet is our closest neighbouring star, Proxima Centauri. It is about 4.2 light years away may have liquid water and the potential to support alien life, a new study has found.
In August, last year, the planet Proxima B was discovered , and is thought to be of similar size to Earth, creating the possibility that it could have an ‘Earth-like’ atmosphere.
Scientists from the University of Exeter in the UK have embarked on their first, tentative steps to explore the potential climate of the exoplanet.
Early studies have suggested that the planet is in the habitable zone of its star Proxima Centauri — the region where, given an Earth-like atmosphere and suitable structure, it would receive the right amount of light to sustain liquid water on its surface.
Now, experts have undertaken new research to explore the potential climate of the planet, towards the longer term goal of revealing whether it has the potential to support life.
Researchers simulated the climate of Proxima B if it were to have a similar atmospheric composition to our own Earth.
The team also explored a much simpler atmosphere, comprising of nitrogen with traces of carbon dioxide, as well as variations of the planets orbit. This allowed them to both compare with, and extend beyond, previous studies.
The results showed that Proxima B could have the potential to be habitable, and could exist in a remarkably stable climate regime.
However, much more work must be done to truly understand whether this planet can support, or indeed does support life of some form, researchers said.
“These frequencies of light interact much more strongly with water vapour and carbon dioxide in the atmosphere which affects the climate that emerges in our model,” said Manners.
