Proxima b: Exoplanet closest to Earth, probably life-friendly
In 2016 astronomers discovered an earth-sized rock planet around the nearest neighbour of our sun, Proxima Centauri, which orbits its star within its life-friendly zone. Since then, the question of whether “Proxia Centauri b” itself is life-friendly or not has been the subject of scientific controversy. A new study confirms again that the planet could be life-friendly despite its active central star.
