Twin Earth Nearby?

A new study from UC Santa Cruz graduate student Javiera Guedes suggests that a planet in the "hospitable zone" for developing water may be formed around the nearby star Alpha Centauri. The study will be published in the Astrophysical Journal, and by using the Doppler detection method (for a period of 5 years) astronomers will be able to confirm if there is a planet there (and if there is it would be a likely candidate for water).
