| Comment |
NGC6188 in the constellation Ara consists of both emission and reflection nebula properties. It harvests an interstellar nursery of young blue stars, blazing red gas and cool dark dust. The two bright stars above the nebula a part of an open cluster known as Ara OB1 (NGC6193). These two stars in the open cluster are so bright that blue light reflects off the surrounding interstellar dust generating a diffused blue glow. The other star members of the open cluster obscured by the gas and dust stimulate hydrogen atoms which produces a vibrant red glow. NGC6188 is located 4000 light-years away. NGC6164-5 (bottom) is a bipolar emission nebula surrounding the massive star catalogued HD 148937. The star is near the end of its life; as a result it is shedding gas. Due to the star's fast rotation and magnetic field, the gas is being expelled in a symmetric shape of the bipolar nebula. Open star clusters: NGC6167 (lower left), NGC6200 (upper right of NGC6188) and NGC6204 (very top right of frame). This image is an LLRGB composite. |
