I first read this article in Astronomy several years ago. It talks about the possibility of life around Alpha Centauri A and B.
This scientific community open of Red Dwarfs, like Alpha Centauri C, is that there is unlikely to be life on any planets orbiting such star. I wouldn’t rule them out. I’m betting life could surprise us.
