Our galaxy, like many others, is a disk with about a hundred billion stars.
The main components are:

Disk (the outer regions of the disk is where our Sun and Solar System lie)
(Nuclear) Bulge, Halo, and (Galactic) Nucleus





And scattered in the Halo around our galaxy are enormous clusters of hundreds of thousands of stars, called Globular Clusters.





Further scattered about our galaxy, mostly in the disk and spiral arms, are open star clusters and nebulae. Each star in our galaxy is an enormous ball of gas, made up mostly of hydrogen.
