Conducting a "cosmic archaeological dig" at the very heart of our Milky Way galaxy, astronomers uncovered the blueprints of our galaxy's early construction phase. Peering deep into the Milky Way's crowded central hub of stars, researchers using our Hubble Space Telescope have uncovered for the first time a population of ancient white dwarfs -- smoldering remnants of once-vibrant stars that inhabited the core. Finding these relics at last can yield clues to how our galaxy was built, long before Earth and our sun formed. This image is a small section of Hubble's view of the dense collection of stars crammed together in the galactic bulge. The region surveyed is located 26,000 light-years away.
