At this time within the historical past of astronomy, a key determine in our understanding of the Milky Manner is born.

- Harlow Shapley earned a Ph.D. from Princeton College in 1913, subsequently conducting analysis on globular clusters and Cepheid variables at Mount Wilson Observatory from 1914 to 1921.
- From 1921 to 1952, Shapley directed the Harvard School Observatory, the place he performed a key function in establishing the college’s graduate astronomy program.
- He’s broadly recognized for his participation within the 1920 “Nice Debate” with Heber Curtis relating to the universe’s scale, although his place on “spiral nebulae” being gasoline clouds throughout the Milky Manner was later disproven.
- Regardless of his incorrect view on spiral nebulae, Shapley’s propositions in regards to the Milky Manner’s considerably bigger dimension, its total form, and the photo voltaic system’s location inside it had been largely correct.
Born Nov. 2, 1885, In Missouri, Harlow Shapley earned a Ph.D. from Princeton College in 1913. From 1914 to 1921, he was posted at Mount Wilson Observatory, the place he used the 60-inch telescope to check globular clusters and Cepheid variables. From 1921 to 1952, Shapley was the director of the Harvard School Observatory, serving to set up the college’s graduate program in astronomy.
Shapley is maybe greatest recognized for his participation within the 1920 “Nice Debate” with Heber Curtis in regards to the dimension of the universe. Though Shapley’s place that “spiral nebulae” (now know to be different galaxies) had been gasoline clouds throughout the Milky Manner was later disproven by Edwin Hubble, the Nice Debate was important for formalizing and weighing the conflicting concepts in early-Twentieth-century astronomy. Moreover, Shapley’s concepts in regards to the dimension of the Milky Manner (far bigger than beforehand estimated), its form, and the placement of our photo voltaic system inside it had been right — or at the very least heading in the right direction.
