Thousands of new models suggest that planets may be life galaxy.

<P> If life on earth really comes from our vast ocean, then a similar situation may also occur in the thousands of other planets. .The new model shows that around the Milky Way about 1 / 3 of the class of galaxies, the solar system may contain Earth-like planets, the planet covered by ocean of water, which is likely to be the cradle of life. .</ P> <P> the new findings to reconsider the composition of the stars before the assumptions, concluded that only a few classes of galaxies may contain the solar system planets like Earth. .Part of the reason and the so-called "hot Jupiters" relevant. .In some classes of galaxies in the solar system, the gas giant planets at very close range - less than the distance between Mercury and the Sun - to run around their parent star, they can from the original protoplanetary disk of gas in a relatively faster rate .formation. .Astronomers speculate that because these hot Jupiter planets in the original plate moves, so they would "suck" a lot of dust and rock, or class of solar system, galaxy throw these substances, and ultimately only the material used to form less .water planet. .</ P> <P> However, the U.S. University of Colorado at Boulder planetary scientist Sean Raymond said: "The new models indicate these early theories is likely to be wrong." In the latest issue of "Science" magazine, .Raymond and colleagues reported that they had this for as long as 8 months of computer simulation. .Based on the modern theory of solar system planets form provided by the original conditions, the researchers simulated a new class of solar system, galaxy about 2 million years in the evolution of time. .The researchers found that when the gas giant planets, they will be far better than many rock stars in the wreckage, which will reach a stable zone, where liquid water can exist on a planet's surface. .These fragments eventually aggregate imaging Earth-like planets. .</ P> <P> way that the early evolution of planets at the same time disrupting the original disk, resulting in billions of kilometers from the comet toward the star. .A lot of hockey hit the planet with the land, which brought a lot of water. .Raymond said: "These planets may be filled with water, or even like the Earth is covered with oceans, we are very surprised." </ P> <P> the University of Arizona, Tucson planetary scientist Rory Barnes said that the research results .that thousands of planets in the Milky Way system are likely to contain Earth-like planets. .However, he stressed that the key issue is how many planetary systems with hot Jupiters. .Barnes believes that the current findings may overestimate the presence of terrestrial planets - the existing method for detecting extrasolar planets "seriously inclined" to find such planets, but "serious neglect" of the solar system like our .study the same galaxy, whose gas giants may be related to their parent stars very far away. .</ P> </ p>.
