The Milky Way galaxy is estimated to have a diameter of 220,000 light-years and began forming billions of years ago. It contains a halo, bulge, and disc, and layers of dark matter surround it. According to Greek mythology, the Milky Way was formed when Hera accidentally spilled her breast milk in the night sky while nursing the infant Heracles.
