Reds are from, "Near-IR Fluorescent Molecular Hydrogen (H2) Emission...(1)" and
"....newly formed hot, massive B-stars with the parent material from which the stars formed.
H_2 emission can act as an indicator of structure, as a thermometer and density indicator and
as indicator of dynamics.     ...photodissociation front...(2)"
