On February 2, 2012, an international team of astronomers lead by Guillem Anglada-Escudé, at Carnegie Institution for Science in Washington D.C, reported the discovery of a fourth exoplanet located in the "habitable zone", neither too hot, nor too cold, rocky, which can have liquid water on its surface and thus arbor life.
This planet called GJ 667Cc is only approximately 50% more massive than the Earth, rotates around its star in 28 days approximately, and is at only 22 light-years from the Earth (our galaxy iss more than 100.000 light-year in diameter).
The same researchers say they have clues suggesting that at least another exoplanet and perhaps two, or even three others are in orbit around same star.
The discovery shows that habitable planets can form in a larger variety of environments than previously thought, the authors say. Their paper is to be published in the scientific journal The Astrophysical Journal Letters.
