Question

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. Shapley's 20th-century observations of globular cluster orbits, which center on a point about 30,000 light years from our Sun, showed we were in the center of the galaxy.

Answer 1

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.
