Habitability Zone
The European Southern Observatory made major headlines with their discovery of an Earth-like exoplanet orbiting our nearest neighboring star. On Dynamics of Cats, Steinn Sigurðsson writes: "ESO researchers, using the radial velocity variability technique, have detected a quite robust signature of a planet with a mass of 1.3 Earth masses, or more, in a 11 day orbit around Proxima Centauri."
