Fantastic shapes lurk in clouds of glowing hydrogen gas in NGC 6188, about 4,000 light-years away. The emission nebula is found near the edge of a large molecular cloud unseen at visible wavelengths, in the southern constellation Ara. Massive, young stars of the embedded Ara OB1 association were formed in that region only a few million years ago, sculpting the dark shapes and powering the nebular glow with stellar winds and intense ultraviolet radiation.
The recent star formation itself was likely triggered by winds and supernova explosions, from previous generations of massive stars, that swept up and compressed the molecular gas. Joining NGC 6188 on this cosmic canvas is rare emission nebula NGC 6164, also created by one of the region's massive O-type stars. Similar in appearance to many planetary nebulae, NGC 6164's striking, symmetric gaseous shroud and faint halo surround its bright central star at the lower right.
The field of view spans about two full Moons, corresponding to 70 light years at the estimated distance of NGC 6188.

Just so we have an accurate frame of referance.
I am about 5ft. & 6in. tall.
I have a son who is just over 6ft.
Now what is that compared to a few light years ?

I can only imagine the unfathomable wonders that lie waiting right there in front of us.
So close, yet so far away.
I quite enjoy this natural human curiosity that drives us into the unknown.
