red object (star?) forcing green in a compression patter from the 3 o'clock to the 7 o'clock position. Much more luminous area's to the right of the image
The red obejct itsself isn't a star, it's 24 micron dust-emission.
But the red emission is likely to be near the central star (cluster) that heats the region.
Indeed the green bow looks like it was compressed by the shock of the HII-region!
