Submission + - Small stars host droves of habitable worlds (nature.com)

ananyo writes: "Planets just like home — roughly the size of Earth and residing at a distance from a star where water would be liquid — are likely to orbit some of the stars nearest to the Solar System, according to a new analysis of data from NASA’s Kepler telescope. The study, which dramatically ups estimates of the number of habitable planets in our galaxy, focuses on the occurrence of Earth-sized planets — which they define as planets having a radius between half and twice that of Earth — around so-called M dwarfs. These are cool, low-mass stars that account for about 75% of the stars in our galaxy."
