Where do the stars in our Galaxy come from? All the stars we see in the night-time sky belong to our Milky Way galaxy, and while most stars were likely born here, in the Milky Way, many appear to have originated in other galaxies and migrated to our shores. Tell-tale evidence comes from streams of stars created when small galaxies interact with the Milky Way. Eleven new stellar streams, discovered in data from the Dark Energy Survey, currently in progress at the NSF’s Cerro Tololo Inter-American Observatory (CTIO), provide new evidence for this picture.
