'Newly discovered Earth-like planet may have oceans'
Recently discovered Earth-like planet Proxima b, which lies in the "habitable zone" of the Proxima Centauri star, may be covered with oceans and support life, astrophysicists at France's CNRS institute have said. Proxima Centauri is about four light-years from Earth and is part of a three-star system called Alpha Centauri, which is the closest star system to the Solar System.
