Astronomers have found the most Earth-like planet outside our Solar System to date, a world which could have water running on its surface. Scientists say the benign temperatures on the planet mean any water there could exist in liquid form, and this raises the chances it could also harbour life.
"We have estimated that the mean temperature of this 'super-Earth' lies between 0 and 40 degrees Celsius, and water would thus be liquid," explained Stephane Udry of the Geneva Observatory, lead author of the scientific paper reporting the result.
"Moreover, its radius should be only 1.5 times the Earth's radius, and models predict that the planet should be either rocky - like our Earth - or covered with oceans."
Xavier Delfosse, a member of the team from Grenoble University believes the planet may now become a very important target for future space missions dedicated to the search for extra-terrestrial life.
These missions will put telescopes in space that can discern the tell-tale light "signatures" that might be associated with biological processes. - Public Radio of Armenia
