Galactic Astronomy & the Milky Way Dataset

The anatomy and life of our Galaxy — the structural components (thin & thick discs, bulge, bar, stellar halo, spiral arms, warp, Galactic Centre, central molecular zone, corona) and the dynamical & archaeological phenomena (rotation & dark matter, stellar streams, radial migration, galactic archaeology, magnetic field, satellite accretion, the Andromeda collision).
