Question:
What is the shape of the Milkyway galaxy?



Replies:
Milky Way has the shape of a disk with a bulge at the center. There is a halo around the galaxy which is spherically symmetric, Globular clusters are its main constituents. The spiral arms of the galaxy are confined to the disk. We are located in the disk, about 25000 light years from the center. The size of the disk is about 75000 light years, from one end to the other.
