New planet almost twice the size of the land and the many similarities (French)
Announced the National Aeronautics and Space Administration (NASA) discovered a new planet, is the most Earth-like planets, orbiting a star lies 600 light-years, a finding that an important part of ongoing efforts to determine whether there is life beyond the solar system?
He joins the planet, called "Kepler 22 B" to the list of discoveries includes more than 500 planet, orbiting stars beyond the solar system, but the new planet is the smallest with a radius of about 2.4 times the half diameter of the Earth, as he is the best location, the presence of water liquid on the surface, one of the elements necessary for life on Earth.
Said Natalie Batallha - Deputy Commander of the scientific team of the Kepler space telescope of the Department of Aeronautics and Space Administration (NASA), who discovered the star - "We are focused on monitoring the planets in the size of the Earth, which can be found by life."
She said in a news conference at the Center for Research, "Ames," NASA, Calif. "I do not know anything about the planets that range in size between the Earth and Neptune, because our solar system does not include models of such planets, and we do not know which part will be rocky and any part contains a reservoir of water Any part contains a reservoir of ice? do not have any idea until we measure one of them and see what they do. "
Scientists said the findings - to be published in the Astrophysical Journal - This is the first discovery of a planet with potential for life orbiting a star like the sun.
The research indicated earlier to the existence of planets about the same size as the earth in areas of viable, but the efforts of scientists demonstrated that it is impossible to live it.
He described Douglas Hadeguens - aparticipant in the world of the Kepler mission at NASA headquarters in Washington - the discovery of new planet as "a landmark eventon the road to reach the Earth's twin."
He added that the findings of the KeplerMission "continues to demonstrate the importance of scientific missions for NASA, which aims to answer some importantquestions about our place in the universe."
NASA said that the mission also observedmore than a thousand horizon can be transformed into planets, although it needs more scientific research, said that this numberrepresents about double the numberannounced by the.
Among the two thousand and 326 planetcandidates Kepler found a team, there are tenin the size of the ground almost, and there aresites make it suitable for life as they spinaround their stars.
If the "Kepler my 22" surface and atmosphereare similar to the land of the temperature it will be 22 degrees Celsius, about the sametemperature in the spring day on the ground.
