A rare perfect symmetry in the Milky Way
According to foreign media reports, astronomers recently discovered through a new study that the Milky Way does not require any "makeup and beauty": it is already perfect. The reason why astronomers came to this conclusion is that they found a spiral "giant arm" formed by planets at the edge of the Milky Way. The discovery shows that the Milky Way has a rare symmetrical beauty-half of the Milky Way is actually a mirror image of the other half.
Thomas Dame and Patrick Thaddeus of the Harvard-Smithsonian Astrophysical Center in Cambridge, Massachusetts, said that the structure they discovered was likely to be a long shield Centaur arm (Scutum-Centaurus) The part that extends from the inside of the galaxy to the outside. The discovery showed that the long shield Centauri arm completely "surrounded" the galaxy, making this spiral "giant arm" commensurate with the other main "arm" formed by planets in the galaxy, the Perseus arm. It is reported that the researchers wrote in an article to be published in the Astrophysical Letters that the two spiral "giant arms" look like they are outward from the center of the Milky Way-the opposite ends of the rod-shaped star cluster Extend, and each "giant arm" surrounds the Milky Way.
It is reported that when Dam studied the data of the atomic hydrogen gas in the Milky Way (the radio wavelength of this gas radiation is 21 cm), he found evidence indicating the existence of the above symmetric structure. Dam said: "After tracing the" extended arm "in 21 cm of radioactive radiation, I was in a unique position, which allowed me to use the radio telescope at the Harvard-Smithsonian Center for Astrophysics to find molecular clouds. Carbon monoxide is emitted, and the molecular cloud of gas contains the original material that created the planet. "
Robert Benjamin of the White Water School of the University of Wisconsin said: "This is a major new discovery. Dam and Sardis discovered evidence of a huge 'quasi-order structure', which has covered more than the sky 60 degrees, and the structure contains a huge cloud of gas molecules far from the center of the Milky Way. â€Dam wrote:“ This newly discovered structure is about 49,000 light-years away from the center of the Milky Way and has a spiral “arm†The giant molecular cloud contains a large amount of carbon monoxide, the amount of which is equivalent to the amount of carbon monoxide contained in 50,000 suns. (Pseudo-ordered structure refers to a continuous large-scale turbulent mass, and there is an associated Vortex, and there is an ordered vortex component, turbulence is composed of pseudo-order and non-quasi-order motion.)
Dam wrote: "Almost every 'arm' in the galaxy has been gradually discovered." It is reported that when astronomers recognized Sagittarius and Carina as a "separate" huge structure , The two have become the famous "human horse-ship base". Dam said: "Similarly, since we believe that the new" arm "we discovered is an extension of the long shield Centaur, we recommend using the" outer long shield Centauri "as a more logical name, and this The new structure is longer than the famous long shield Centaur arm. It will take a few years to map all the carbon monoxide in the new structure. But this new discovery reveals the symmetrical view of the Milky Way plus the previously discovered Evidence that the study of the spiral structure in the Milky Way is simpler and easier than people have thought for a long time.
