The center of the Galaxy is separated by a mysterious barrier. How and for what purpose did it form?
➤ review “could looks like, the good luck body is in the mountain”, like we have today, although the outside can see the Milky Way galaxy, but we even know very little about the actual situation of the Milky Way, as affected by a large number of interstellar dust, even today, we can see clear “busy” area at the center of the Milky Way galaxy.Of course, there must be countless secrets hidden there, too.➤ recent discoveries of Chinese Academy of Sciences, the isolation barrier at the center of the Milky Way galaxy as we all know, the environment inside are full of cosmic rays, the radiation is essentially told sport with a subatomic particle, more small than the atomic structure, most of them are protons, of course, there are few other elements nucleus (helium atoms and trace electronic).If the cosmic rays are traced back to their origin, they may come from supernovae, pulsars, black holes, quasars, and the energetic activities of stars. Studying cosmic rays in the Milky Way will help us better understand our own galaxy.But want to directly observed cosmic rays are not realistic, astronomers only through an indirect way of observation, cosmic rays in the process of its spread, and there will be a certain probability molecules, such as dust and gas interstellar medium, when the works will release after high-energy gamma rays photon, and this photon, can be observed.Astronomers from the Chinese Academy of Sciences (CAS) collected data using the Gamma-ray Large Area Space Telescope (GAMMA-Ray Large Area Space Telescope) in this way, and after in-depth analysis of the data, they discovered this “strange” phenomenon: the density of cosmic rays in the molecular cloud in the central region of the Milky Way galaxy is much lower than that in other regions.Why is that?As mentioned above, cosmic rays come from many sources. On this basis, charged particles of cosmic rays are repeatedly deflected by magnetic fields in various galaxies in their path, so the density of cosmic rays should be uniform at the level of the entire galaxy.The lower density of cosmic rays in the central region of the Milky Way suggests that a mysterious force, or barrier, seems to be blocking cosmic rays from entering the molecular clouds there.More intriguingly, the study identified A large source of cosmic rays in the Milky Way’s central region. The source, the researchers speculate, is probably the galactic black hole Sagittarius A*.The mass of the giant, already 4.3 million times the mass of the sun, may have been the result of the massive cosmic rays still accreting around it.But it’s also the most puzzling question of all. Why is the density of cosmic rays so much lower at the center of the Milky Way, which itself has a huge source of cosmic rays?This suggests that the mysterious barrier at the galactic center is likely a “one-way open” state, meaning that the vast amount of cosmic rays that form there can be emitted outwards, but those from outside can’t get in.➤ What’s up with the mysterious barrier at the center of the Galaxy?Perhaps the center of the Milky Way galaxy is actually a “thriving” scene, or perhaps an advanced alien civilization lives there and uses more advanced technology to build the barrier to protect it.The idea is not impossible, of course, because a barrier that protects against cosmic rays would be extremely powerful, and it would protect against many other threats as well.Of course, we have to admit that the above speculation is highly unlikely, given the extremely dense stars at the center of the Milky Way galaxy, where the environment is filled with huge amounts of gamma rays, X-rays and other radiation.And the stars at the center of the Milky Way are so close together that their respective gravitational forces interfere with each other, making them inherently unstable and therefore inhospitable to life.Of course, in my own opinion, what we call life today is life as we know it, but exactly what form extraterrestrial life will take is anyone’s guess.Like oxygen and water, the things we know life needs today, but do aliens really need oxygen?Who knows.”➤ finally to sum up, the Chinese Academy of Sciences, astronomers discovered that mysterious barrier we don’t know its cause and purpose, a reasonable guess now has two kinds: (1) areas there are a large number of stars at the center of the Milky Way galaxy, a large number of stars to form the “star” wind, they gathered in there, in a specific way and stop the cosmic rays;2. The collapse of the dense cloud of dust and gas at the galactic center has compressed the magnetic field there over time, thus creating a barrier against cosmic rays.Details of the study are also published in Nature Communications, and those interested can check them out for themselves.
