- mr_toad 2y agoThere are estimates that half the matter, including the older stars in our Galaxy came from other galaxies that were absorbed long ago (10B+ years) by the Milky Way. The younger stars have been formed here in the disk. So on average a large portion of the oldest stars tend to have been from elsewhere, whereas the newer stars were born here.
