The Milky Way deviates from textbook four-armed symmetry: young Cepheid kinematics reveal a complex, multi-arm morphology where the Perseus and Norma arms dominate as inner anchors while secondary arms split into extended branches out to 15 kpc.
Far-side spiral arms of the Milky Way converge toward a single inner-Galaxy feature, providing the most direct astrometric evidence to date for a bifurcated Galactic disc architecture.
