APOD: NGC 6188 and NGC 6164 (2016 Mar 30)

Image NGC 6188 and NGC 6164

Explanation: Fantastic shapes lurk in clouds of glowing gas in the giant star forming region NGC 6188. The emission nebula is found about 4,000 light years away 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, visible toward the lower right, 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 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. Three image sets have been included in the featured composite.

Colors are spectacular! When I was a boy, all astronomical photographs were black-and-white!

From here on Earth this colorful vista spans the width of 6 full moons - and it's only 200 light years distant? It's virtually in our cosmic backyard!

  • That was a different Ara.

When an astronomical image makes one want to get keep looking deeper and deeper into its content I think the goal of imagery coupled with artistry has been accomplished. Great job! :clap:
