Recent research by astronomers suggests that the Milky Way formed about 13 billion years ago

On March 24, the international scientific journal Nature published a major scientific research result of the collaboration between Dr. Mao Sheng Xiang and Professor Hans Walter Rex at the Max Planck Institute for Astronomy in Germany. Based on sky survey observation data from the Guo Shoujing Telescope LAMOST and the Gaia Telescope, an astrometric satellite run by the National Astronomical Observatory of the Chinese Academy of Sciences, astronomers restored early images of the Milky Way. The results reveal the history of the early formation and evolution of the Milky Way. The research team believes that the integration and evolutionary history of the Milky Way is divided into two distinct phases, from the early stages from 13 billion years ago to 8 billion years ago and the late stages from 8 billion years ago to the present.
