Target:
Fighting Dragons of Ara (NGC6188).
Distance to Earth: 4,000 light years.
NGC 6188, The Fighting Dragons of Ara, is an emission nebula in the constellation of Ara. It gets its name from the apparent silhouette of two dragons engaged in a cosmic combat.
Due to its hydrogen-rich clouds, NGC 6188 is a region of active star formation, and its structure is shaped by the powerful stellar winds of the young and massive stars within.
The glowing bipolar planetary nebula, NGC 6164, is visible at the bottom of the frame, which some liken to being like the "dragon's egg".
