👤 whose
Whose discovery showed that the Sun is orbiting within the Milky Way rather than ruling the center of everything?
Quick Answer
Friedrich Bessel’s work and later astronomy showed the Milky Way’s structure, but the decisive model came from Harlow Shapley. In the early 20th century he placed the Sun away from the galactic center.
The Full Story
Harlow Shapley used Cepheid variables in globular clusters to map the size and structure of the Milky Way. In the 1910s and early 1920s he concluded that the Sun is not at the center of the Galaxy. His work shifted astronomy’s view of humanity’s place in the cosmos. Shapley’s model was a major step toward the modern picture of the Milky Way.
