CentralBulge

the "central bulge" of the Milky Way operates at an angle to galatic arms.

Here is a depiction of the star cluster forming the "central bulge" at galactic core seen in infrared. Notice the central core is located to the left in this picture, and that a small spiral of stellar nebulae has formed around the exact central point of our galaxy, which appears here as a samll, bright white star at the centre of the spiral on the left.
