Hi that is a separate nebula complex call the Dragon's Egg. It has two designations, NGC6164 for the inner area and NGC6165 for the outer bubble. The star at the center created everything. Known as the Dragon's Egg, this star -- a rare, hot, luminous O-type star some 40 times as massive as the Sun -- created not only the complex nebula (NGC 6164) that immediately surrounds it, but also the encompassing blue halo. Its name is derived, in part, from the region's proximity to the picturesque NGC 6188, known as the fighting Dragons of Ara. In another three to four million years the massive star will likely end its life in a supernova explosion.

Basically the star goes through periods where it blows its outer shell off into space. It looks far better in normal light. This website shows a far better image of it in the visible light spectrum https://apod.nasa.gov/apod/ap140522.html
