E2 - at larger radii

• the distribution of G, K stars flatten out following the power law
• there is a spherical distribution of stars
• it ids consistent with the distribution of globular clusters

• old, low metallicity globular clusters fill a spherical space, forming a halo of globular clusters (${10}^6$ stars, up to $50$ kpc from the centre
• young, high metallicity globular clusters are on a plane
