Astronomers may just found the first candidate for an earthlike planet. It 20 light years away and orbits an M-class start. It is larger than the earth and tide locked to it's star. Which means it's day is as long as it's year. It is orbiting right in the middle of the zone that supports liquid water.
Since M-class stars are so common this is good news to finding more earthlike world. The only bad part of the discovery is that the planet doesn't transit the star so they don't have any tools yet to analyze it's atmosphere.
Time for Traveller Fans to start updating their charts.
