The rotating gas cloud is a good one not included.
In the center of the galaxy Hercules is a supermassive black hole that absorbs large amounts of material, and forms a rotating disk with a temperature so high that it wants to expand and explode violently. Among the magnetic forces, friction and other, the material is strongly driven by two rays that come from the poles of the disk so fast that travel hundreds of light years before settling down in speed and the two red clouds observed in the image.
The overall structure has more than a million light years from end to end, but what you would expect from an object whose main engine is a black hole with 2,500 million times the mass of the sun?
Behold the Heavens in all their glory.
