Answer:
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.
Step-by-step explanation:
- The structure of our galaxy is formed by the six paths as the nucleus, the central bulge a disk, has spherical arms ad spherical components and surrounded by a huge and large halo. Being a disk-shaped this galaxy is spiral in nature and denser stars are closer to the galaxy.
- The milky way is located about 30,000 light-years away from the sun and its galactic center is far from the center which is dominated by a supermassive black hole.
