Description

NGC 6188 is an emission nebula in the Ara constellation, around 4000 light years from earth.

The shapes/patterns throughout the nebula are the result of stellar winds emitted by massive nearby stars. The colourful palette is caused by the ultraviolet radiation of these same stars. The entire process was more than likely triggered by supernovae from previous generations of stars compressing the gas enough to kickstart the whole thing.
