The findings support a decades-old hypothesis that there should be tens of thousands of stellar mass black holes at the galactic centre. *First age map of the heart of the Milky Way The first large-scale age-map of the Milky Way shows that a period of star formation lasting around 4 billion years created the complex structure at the heart of our galaxy. Previous studies have shown that the bulge hosts two components -- a population of metal-poor stars that have a spherical distribution -- and a population of metal-rich stars that form an elongated bar with a “waist,” like an X or a bi-lobed peanut. *Discovery of the most distant star ever seen. Astronomers have spotted the most distant star they’ve ever seen. The star dubbed Icarus is a
