Study found that the solar system with the Milky Way separatist.
World Scientific reports [tech.] News: According to foreign media reports, U.S. scientists found that the rest of the solar system and the Milky Way runs in a different direction, is the Milky Way "separatism." .They run through the two spacecraft in interplanetary space back of the radio signal, the operation of the solar system to map out routes and found some surprising results. .<P> Researchers found that the magnetic field in interplanetary space are driving other parts of the Milky Way solar system into operation 60 to 90 degree angle. .The reason this happens is because the nearest part of the solar system from interstellar magnetic field is not as it looks like in other parts of the galaxy, with arms parallel to the rotation of the Milky Way. .George Mason University in Virginia, Associate Professor Pamela Fuao Poole (Merav Opher) said, the result is that across the vast universe, the solar system would take the shape of warheads appeared. .The results published in the latest issue of "Science" magazine. .</ P> <P> researchers used two 30-year history of "Voyager" spacecraft data and computer models to calculate the position of the solar system. .Relevant data to measure the solar system, scientists will study the solar influence is usually the end of the beginning of interstellar space and the area that is called "heliosphere" (heliosphere). .Territory occasionally drifted across the solar system called the solar wind ion particle flow, like a bubble, fenced round and round, like the solar system. .Outside the bubble is interstellar space, most of the hydrogen and helium. .The researchers used computer models to simulate the heliosphere encounter the interplanetary magnetic field region, discovered the strange angle. .</ P> <P> University of Arizona professor 兰蒂约克佩 (Randy Jokipii) in "Science" magazine, pointed out the relevant paper, by studying the heliosphere and interstellar space interaction between the scientists can influence the .Earth phenomena (such as galactic cosmic rays) have a deep understanding. ."Voyager 1" spacecraft has been through the outer bubble of solar wind is currently exploring a sheath called the day (Heliosheath) the transition zone. ."Voyager 2" spacecraft through the solar wind has yet to end zone. .Scientists also plan to use two "travelers" spacecraft, the Sun and Heliospheric (SOHO) and interplanetary exploration border (IBEX) spacecraft, in-depth study on this. .Spacecraft to explore interstellar boundary is expected to be launched next year. .</ P> </ p>.
