According to the latest research results show that   the Milky Way department is expected to face painted on the Shaanxi channel: people.com.cn original title: the Milky Way department is expected to face painted on people.com.cn September 29 Nanjing Xinhua (reporter Yao Xueqing) the day before, to Chinese Academy of Purple Mountain Observatory scientists as the main members of the project team of Bessel through the study found:. The main structure of the Milky Way arm system not only has a smooth rule, also has from the arms raised "fork" or even "bridge". The latest research results were published in Science, Advance, a sub issue of the international top academic journal "Science" at 2 p.m. Eastern time on September 28th, and will be reported as a bright spot (highlights). In many popular science books, the Milky Way system is composed of an interstellar material of billions of stars and countless spiral galaxies, consisting of a core and 2 or 4 arms. The spiral arm is a characteristic structure of spiral galaxies, and the bright bands, from the center of the earth, circle around each other until the edge of the galaxy. The bright spots on the spiral arms are massive star forming regions. Our solar system is located in the innermost part of a mass of young stars that are called the local arm or Orion Arm because of its proximity to orion. It’s hard to look at the whole picture in the Milky way. However, as long as we can accurately measure the distance between the massive star forming regions on the Milky Way’s spiral arm, it is like a nail on it, and a bunch of nails can be assembled to draw the spiral arm shape of the Milky way galaxy. The structure of the Milky way is actually much more complex." The main members, the Bessel project Zijinshan Observatory researcher Xu Ye said, they found a local department of the Milky Way raised arm, it is like a bridge from the local arm extends to the Sagittarius Arm, about 12 thousand light-years long, is a projection of the Milky Way system found so far the longest. Xu Ye introduced, it will be shown that the Milky Way not as people previously imagined, only by the magnificent spiral galaxy is composed of the main spiral arms, and more likely to be the main spiral arms of spiral galaxies have a rich structure, in addition to a major arms such "branches", also has a "" on the bifurcation branches. Based on this study, the Milky Way looks promising again.
