The Milky appearancehttp//seds.lpl.arizona.edu/messier/more/mw_sky.htmlThe Milky Way is the home of our Solar System along with at least two hundred billion other stars and planets. It births thousands of clusters and nebulas. It is the home of nearly altogether the objects of Messiers catalogue that bent their own galaxies. The mass of our giant beetleweed is somewhere amongst 750 billion and one trillion solar masses. The diameter is estimated to be about 100,000 escaped years. The galaxy has three main components a disk, in which the solar system resides, a central appear at the core and an all encompassing halo. The disk of our galaxy exhibits its handbuild structure and is originate of the prominent nuclear region which is part of a notable bulge/halo component. http//www.damtp.cam.ac.uk/user/gr/public/gal_milky.html The Milky Way is categorized as a Hubble type Sb or Sc spiral. It is unclear if the galaxy has a bar in its spiral so that is why its mixed bag is unsure. The image above is that of the spiral galaxy M83, which is public opinion to be akin(predicate) in size and shape to our Milky Way, causing some to submit our galaxy as a Abbc type spiral. The bright ban of light seen at night, is usually what is referred to as the Milky Way. The bright plane is real the disk of our galaxy. The disk is composed of mostly Population 1 stars, which are blue and fairly young, which range between a million and cristal billion years old. The disk of our galaxy has four spiral ordnance, which contain interstellar matter, diffuse nebulae, and young stars and open star clusters emerging from that matter. The spiral arms are withal where the active star formations take place. The arms are approximately 300 pc thick and 30 kpc in diameter. The red stars, or the older stars, in our galaxy are set(p) in the bulge component, which is the content of our galaxy. These Population II stars are thought to be 10 billion years o ld. The bulge component also contains the globular star clusters. It is estimated that our galaxy has about 200 globulars, but we make do about 150. These globular clusters are consolidated toward the Galactic Center. Harlow Shapley concluded that the center of the Milky Way lies at a cpnsiderable distance in the focusing of Sagittarius.
