Planetary Nebulae, Globular Clusters and the Galactic Halo45°) with the number of planetaries in globular clusters suggests that (to within a factor of 2 or 3) the galactic halo has a luminosity .. ≃ 2 × 10.... From the work of Oort it is estimated that the galactic halo has a mass of . 6 ×10.M. so that M/. > 30 for the galactic halo.
