你在哪里可以看到龙在夜空中打斗？在圣坛的南部星座：阿拉。当然，这些龙实际上是由形状令人联想的气体和尘埃构成的。神话中战斗野兽的天堂家园被编目为NGC 6188，位于大约4000光年外，靠近一个巨大分子云的边缘。嵌入天ara OB1星团的大质量年轻恒星形成于几百万年前，塑造了黑暗的形状，并以恒星风和强烈的紫外线辐射为星云发光提供动力。与NGC 6188一起出现在这张宇宙画布上的是不寻常的发射星云NGC 6164，它也是由该地区的一颗大质量恒星产生的。这张令人印象深刻的广角照片拍摄于澳大利亚昆士兰，跨度超过2度（四个满月）。

Where can you find dragons fighting in the night sky? In the southern constellation of the Altar: Ara. The dragons are, of course, actually made of suggestively shaped gas and dust. The celestial home of the mythological battling beasts is cataloged as NGC 6188 and located about 4,000 light years away near the edge of a large molecular cloud. Massive, young stars of the embedded Ara OB1 association were formed there only a few million years ago, sculpting the dark shapes and powering the nebular glow with stellar winds and intense ultraviolet radiation. Joining NGC 6188 on this cosmic canvas, visible toward the lower right, is unusual emission nebula NGC 6164, also created by one of the region's massive stars. This impressively wide field picture, captured from Queensland, Australia, spans over 2 degrees (four full Moons).
