Expert Solution

Globular clusters are not located in the spiral arms of the milky-way galaxy.

Explaination:

(a)O-tye and B-type stars are typically located in the regions of active star formation such as a spiral arms of a spiral galaxy.

(b)when stars are born ,they devolop from large clouds of molecular gas.These stars form a cluster which usually found in the arms of our spiral milky-way galaxy.

(c) Bright emission nebulae and hot , young stars are usually present in the spiral arms of spiral galaxy.Emision nebulae are the sites of recent star formation .

(d)Globular clusters are old clusters of stars that have remained in the gravitationally bound system .They are found in the spherical halo of the milky-way galaxy .Hence they are distributed above , below and level with the plane of flat,disk shaped milky-way.

(d)Dust lanes are also located in the spiral arms of the milky-way galaxy .

Spiral arms result from density waves in a disk galaxy. Star formation occurs in these arms. As the material in a galaxy interacts with a spiral density wave, clouds compress and dust lanes form. Then, the dense gas clouds ignite with star formation. What is the evidence in this image that supports the claim that the stars are moving faster than the density waves? A. Bright stars can be found on the leading edges of the arms. B. Bright stars...

We’ve learned in class that most of the gravitating mass in the Milky Way is in some form of “dark matter”. In a few paragraphs below, briefly describe how we measure the presence and properties of this dark matter in our galaxy, and discuss at least one possible 'solution' to the mystery of what dark matter is.

Our Sun, with mass 2.00×1030 kg, revolves about the center of the Milky Way galaxy, which is 2.20×1020 m away, once every 2.50×108 years. Assuming that each of the stars in the galaxy has a mass equal to that of our Sun, that the stars are distributed uniformly in a sphere about the galactic center, and that our Sun is essentially at the edge of that sphere, estimate roughly the number of stars in the galaxy.
