Title:
Reflections on NGC 6188
Explanation:
NGC 6188 is an interstellar carnival of young blue stars [ http://antwrp.gsfc.…], hot red gas [ http://antwrp.gsfc.…], and cool dark dust [ http://antwrp.gsfc.…]. Located 4000 light years away in the disk [ http://antwrp.gsfc.…] of our Galaxy, NGC 6188 [ http://www.aao.gov.…] is home to the Ara OB1 association [ http://adsbit.harva…], a group of bright young stars whose nucleus forms the open cluster NGC 6193 [ http://adsbit.harva…]. These stars are so bright that some of their blue light reflects off of interstellar dust [ http://antwrp.gsfc.…] forming the diffuse blue glow in the center of the above photograph [ http://www.aao.gov.…]. Open cluster [ http://www.seds.org…] NGC 6193 formed about three million years ago from the surrounding gas, and appears unusually rich in close binary stars. The red glow visible throughout the photograph arises from hydrogen [ http://www.chemical…] gas heated by the bright stars in Ara OB1. The dark dust [ http://www.pha.jhu.…] that blocks much of NGC 6188 [ http://www.geocitie…]'s light was likely formed in the outer atmospheres of cooler stars [ http://antwrp.gsfc.…] and in supernovae ejecta [ http://antwrp.gsfc.…].
