According to the traditional theory, the galaxy formed from a large spherical cloud of gas that collapsed under its own gravity. As the gas collapsed, it formed a rotating disk, and the central region of the disk eventually formed into the galaxy's bulge. The remaining gas and dust in the disk continued to rotate, and over time, they formed into the galaxy's spiral arms, where most of the stars in the galaxy are located.
