The cavernous crimson area on the right aspect of W51 is more mature, evident in the way in which it's got presently been carved out by winds from generations of huge stars (those at the very least ten times the mass of our Sun).
The heat of creation smashed atoms along with plenty of pressure to break them up into a dense plasma, an opaque soup of protons, neutrons and electrons that scattered gentle like fog.
