The story of how we came to learn the structure of the Milky Way is an excellent example of how science progresses. Part A Select the сorrect statements. Check all that apply. Check all that apply. The Milky Way is much wider than it's thickness. So it is a narrow band with many stars in it, while the sky outside the band has much fewer stars. Shapley's 20th-century observations of globular cluster orbits, which center on a point about 30,000 light years from our Sun, showed we weren’t in the center of the galaxy. The Milky Way is not wider than it's thickness. We see stars distributed more or less evenly across the sky.
