NGC 6188, lies 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.
On this image there is another 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 near the bottom edge. The impressively wide field of view spans over 3 degrees (six full Moons), corresponding to over 200 light years at the estimated distance of NGC 6188
