Astronomers have discovered what they say is the most Earth-like planet yet detected — a distant, rocky world that’s similar in size to our own and exists in the Goldilocks zone where it’s not too hot and not too cold for life.
Elisa Quintana and Thomas Barclay are both research scientists at the SETI Institute at NASA’s Ames Research Center and the astronomers who discovered the planet.Speaking from Mountain View, California, they discuss what makes the planet earth-like and what are the chances it can sustain life.
