It is official now, astronomers have discovered a planet in the Habitable Zone of our closest star, Proxima Centauri. The planet Proxima-b has a minimum mass of the planet is 1.3 Earth masses (30% heavier than Earth – or more) and it is in the empirical Habitable Zone of its star (meaning gets less flux than Venus and more than Mars) – a very exciting and inspiring find. A potentially habitable planet around our closest star, at our cosmic doorsteps!
Its star, Proxima Centauri, is a small red star, that is very active, bombarding the planet every 10-30 hours with high energy radiation. With lot of high energy radiation hitting the planet, biota (if it is there) could evolve to cope with it, e.g. shielding itself through biofluorescence… so a potential biofluorescent world around our closest star. And we can look with E-ELT the next big telescope in Chile (40m diameter, to start observing 2022)… exciting times…..
