From within the spiral arms of our own galaxy, humanity has long struggled to see where home truly ends. Now, astronomers have identified a hard boundary at roughly 40,000 light-years from the galactic core — closer than prevailing models ever suggested — where star formation ceases not gradually, but abruptly. This revision to our map of the Milky Way is also a revision to our understanding of how galaxies define themselves, and why the universe imposes limits on the places where new suns are born.
