The latest discovery is that the center of the Milky Way galaxy ejects dense cold gas, just like a bullet.

  According to foreign media reports, an international research team discovered that the center of the Milky Way galaxy jets dense cold gas, just like bullets.

   How these gases are ejected is still a mystery, but the Australian National University professor Naomi McClure-Griffiths (Naomi McClure-Griffiths) Said that their findings may have important enlightenment for the future of the Milky Way.

   Griffith said:“The galaxy is very good at’lifting a rock and hitting itself in the foot’. When the galaxy releases a lot of mass, it will lose its use Star-forming matter, if the galaxy loses enough matter, it will not be able to form a star.”

   So it is very exciting to observe the Milky Way’s loss of star-forming gas Exciting things that make you wonder what will happen next? At the same time, this latest study also raises new questions about what is happening in the center of the galaxy!

   Griffith said:“Since the discovery of the so-called’Fermi bubble’ 10 years ago, the wind at the center of the galaxy has been a topic of controversy. Bubbles are two huge spheres filled with hot gas and cosmic rays.”

   We have now observed that there is not only hot gas in the center of the Milky Way, but also dense High gas, cold gas will be heavier, so it is not easy to move.

   There is a huge black hole in the center of the Milky Way, but scientists do not know whether the black hole will release gas or whether thousands of massive stars in the center of the Milky Way are blown away. The author of the research report Johns Hopkins University Dr. Enrico Di Teodoro said that we do not Knowing how black holes or star formation produce this phenomenon, we are still looking for conclusive evidence, but as our understanding deepens, the situation will become more and more complicated.

   This is the first time this phenomenon has been observed in the Milky Way, and we have observed such processes also appearing in other galaxies. However, other galaxies outside the Milky Way may have larger black holes and more active star formation, making it easier for galaxies to disperse matter.

  Teodoro said that there is a technical bottleneck in observing galaxies outside the Milky Way, and we cannot get a lot of detailed data. The Milky Way is like a laboratory. We can enter this laboratory and observe the operation of things in the universe up close. It is reported that the bullet-like gas in the Milky Way was observed by the Atacama Pathfinder Experiment (APEX) of the European Southern Observatory (ESO) in Chile. The research report was published in the journal Nature. (Ye Qingcheng)
