    Description

    This emission nebula is found near the edge of a large molecular cloud unseen at visible wavelengths, in the southern constellation Ara. New stars 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. This nebula is distant 4.000 light years and comprises of a planetary nebula, just barely visible in this image (on hte lower left hand) and some patches of dark nebulas.

    Now that I have my telescopefixed, I am thinking to re-do this image with a best framing and some more subs.
