Herschel was the first to recognize the structure of the galaxy. By conducting a large number of star counts, Herschel found that stars were more in the galactic plane and in the Milky Way and there were less toward the celestial poles.

Moore’s first published writing was “Observations on the Problem Respecting the Radius of Curvature,” in Nicholson’s Journal of Natural Philosophy (1808). In 1810 he was prompted to investigate the ballistics of rockets when the Royal Danish Academy of Sciences offered a prize for the best paper describing the motion of rockets. Moore examined hypothetical rocket motion, both with and without air resistance, but did not submit a paper.
