La bildo estas kopiita de wikipedia:en. La originala priskribo estas:
Observed spiral structure of the Milky Way galaxy following Taylor, J.H. & Cordes, J.M (1993). Pulsar Distances and the Galactic Distribution of Free Electrons, Astrophysical Journal, 411: 674-684. The arrow points the direction of the solar system's motion relative to the spiral arms. The plotted orbit of the sun does not account for perturbations caused by interactions with the spiral arms.
