Global space news: the conditions of planets around M-dwarf stars
In 2016, astronomers announced a thrilling discovery. A small planet had been discovered around the nearest star to the Sun, Proxima Centauri. The planet's orbit was just 11.2 days, but the small size and corresponding lower luminosity of Proxima Centauri compared to our Sun meant that this planet was in the habitable zone, receiving similar levels of radiation from its star as the Earth. So could the surface of our nearest neighbour actually be habitable?
