This is a really cool picture of NGC 6188. This emission nebula is located about 4000 light-years away in the constellation Ara. The glow comes from the intense ultraviolet radiation and stron winds emitted by the young stars in this cluster which is only a few million years old. The area of young stars likely developed as a result of strong winds and supernova explosions that may have compressed molecular gas. Spanning about 300 light-years across, the false color photograph was taken by the Hubble. The colors come from the ionization of hydrogen, sulfer, and oxygen, which create red, green and blue shades in this picture. This nebula can be seen in the Southern Hemisphere, although it requires a very strong telescope to see the large cloud in any detail.
