The loops at the top of this nebula are formed by the surging stellar winds produced by the hot new blue stars hidden throughout the interior and are also ionising the clouds which you see here as glowing red. Some oxygen is thawed from the dusty clouds when the new stars burst into life which you see here as the blue regions indicating the densest and hottest areas of star creation.
