NASA zooms in on 10,000 Sun-like stars in the Milky Way
NASA astronomers have used the Hubble Space Telescope to study the composition and motion of 10,000 Sun-like stars, as seen in the inset image of the Milky Way galaxy. Analysing nine years' worth of data, astronomers have made a three-dimensional chart of the bulge and found chemically enriched stars were moving twice as fast as the other population.
