Astronomers have identified the precise boundary of the Milky Way's star-forming disk, marking a significant breakthrough in understanding our galaxy's structure. The research revealed that the youngest stars are located at the edge of this disk, while beyond this boundary lies a population of ancient stars that migrated billions of years ago. This discovery helps clarify the complex evolutionary history of the Milky Way and provides new insights into how galaxies form and develop over cosmic time scales.
