The correct option.

Answer to Problem 1QQ

The option (b) is the correct answer.

Explanation of Solution

Introduction:

Galaxies can be classified on the basis of shapes and into three main categories: Spiral, Elliptical and Irregular. Spiral galaxies have three main parts: bulge, halo and disk. Bulge is present in center. It contains old stars mostly. The disk contains young stars and forms the arms of the galaxy.

Halo is a loose structure that surrounds the bulge and some parts of disk. The old star clusters or the globular clusters lie in the halo part of the spiral galaxy.It is not the dominant region which is crowded with starsand is called the galactic central region. It is also not like a pancake region. Hence, both options a and c are not right.

Conclusion:

Therefore,a halo of the galaxy is a large, roughly spherical region surrounding the disk.

PLEASE be clear in your answer since the last time I posted was incorrect, and only answer part b, thanks.

Why I got it wrong? Please help me to provide just few summary.

Think of our Milky Way Galaxy as a flat circular disk of diameter 100,000 light-years. Suppose we are one of 1000 civilizations, randomly distributed through the disk, interested in communicating via radio waves. How far away in light years would the nearest such civilization be from us on average? Show your working. (Hint: Begin by calculating the area of the disk. Find the area of one of a 1,000 squares. Consider the separation of the centres of two adjacent squares.)
