You want to observe individual stars in a globular cluster; this cluster has 106 stars distributed within a sphere of characteristic radius of 1 parsec. Estimate the distance, in kiloparsecs (kpc), out to which the Hubble Space Telescope (HST) ought to be able to resolve individual stars within the cluster. You should assume that the HST has a mirror of diameter 2.4 m, and works at a wavelength of λ = 0.5 μm. (You will need to look up how...
