The shape of the Milky Way is more easily revealed by looking at the distribution of star clusters rather than of stars. The clusters are not randomly distributed: the open clusters lie in the plane of the Milky Way and define the galactic disk, and the much more populous globular clusters form a spherical cloud around the disk called the galactic halo.
NASA, ESA; adapted by E. Otwell. By the end of the century, astronomers knew that the universe was dotted with billions of galaxies of all shapes and sizes. In April 1990, NASA launched the first NOVA Universe Revealed: Age of Stars Preview. “Milky Way” Premieres Wednesday, Nov. 3 at 9 p.m. on KPBS TV + Sunday, Nov. 7 at 9 p.m. and Monday, Nov. 8 at 7 p.m. on KPBS 2 / On Demand - The Also, the difference between the Milky Way and other spiral galaxies can be justified by the method of observation, which relies on stars in the former, and on gas clouds in the latter. Meanwhile, Françoise Combe believes that the Milky Way Galaxy “is not exceptional at all,” but in terms of dark matter, “it is like the others.” 1696122839This little known plugin reveals the answer. In addition to the sun, our galaxy, the Milky Way, is believed to have up to 400 billion stars. The Sun and the solar system also revolve around the center of our galaxy, the Milky Way. The period of this revolution is extremely long, taking approximately 200 million years.So the question is that is that is Milky Way is orbiting around some object or perhaps Black Hole. Same idea. There is no single point-object nearby massive enough for our galaxy to "orbit" around it. Our galaxy, along with Andromeda, and a handful of other galaxies, are bound together in what is known as the Local Group. .
