Researchers at the Observatories of the Carnegie Institution say a newly discovered star outside the Milky Way has shown important clues about the evolution of our galaxy. Located in the dwarf galaxy Sculptor some 280,000 light-years away, the star has a chemical make-up similar to the Milky Way's oldest stars, supporting theories that our galaxy grew by absorbing dwarf galaxies and other galactic building blocks. Pectroscopic measurements of the star's light at Carnegie's Magellan-Clay telescope in Las Campanas, Chile, determined it to have a metal abundance more than 4,000 times lower than that of the sun -- five times lower than any other star found so far in a dwarf galaxy.
