Its size I'm told is 50 LY,and its about 7,000 LY from me(fine) I look
at it every morning,and always wanted to ask this question. How did it
create such a shape? Why do points,or lumps stick out of this cloud?

Once massive stars form, they tend to disperse the nearby nebula due to
radiation pressure and high speed "solar winds". The nebula gets sculpted by
the stars it forms. Futher to this, the supermassive stars eventually
detonate as type II supernova, the resulting shock triggering more star
formation.
