Kepler-22b, a planet predicted to potentially accommodate life (space.com)Twin Earth has an atmosphere, water, and the average temperature of 22 degrees Celsius.Scientists United States Space Agency (NASA) reveals the existence of planets that could support life (habitable). His name, Kepler-22b. Discovered by the Kepler space telescope.Scientists continue to examine the "twin Earth" that. Based on recent research, identified Kepler-22b is twice the size of Earth, with an average temperature of 22 degrees Celsius.Kepler-22b has an atmosphere that can support life. Almost perfect, except for this shortage: the distance is too far away, 600 light years from Earth.Kepler 22-b adal ah who first referred to as "super-Earth" known to lie in the habitable zone, with a star similar to our sun.Dubbed the "Goldilocks Zone", the location where the planet is having a suitable temperature, which allows the existence of water on its surface.This means the planet could have continents and oceans - as well as the Earth. For where there is water, that's where life is.Scientists believe Kepler-22b can not just be able to support life, but also possible, is there life there."These findings support the belief that we live in a universe crowded with life," said Dr Alan Boss, of the Carnegie Institution for Science in Washington DC - who helped identify the planet from data obtained by the Kepler space telescope, such as published by the Telegraph, December 6, 2011.As is known, the Kepler telescope launched by NASA oversees 1 55 000 stars - to find the existence of habitable planets.Star in orbit around Kepler-22b, is in the constellation Lyra and Cygnus - smaller than the sun and 25 percent more dim.The planet orbits its star in 290 days, with a 15 percent closer than the distance of Earth to the Sun.Kepler-22b is located right in the middle of the habitable zone of stars - the perfect conditions for life.Meanwhile, two other planets orbiting stars smaller and cooler than the Sun - was recently discovered on the edge of the habitable zone of their mereka.Orbit more similar to Mars and Venus.The report on the findings will be published by the Astrophysical Journal.Dr Douglas Hudgins, Kepler program scientist at NASA headquarters in Washington, said, "This is a milestone to finding Earth's twin."
