Explanation: East of Antares, dark markings sprawl through crowded star fields toward the center of our Milky Way Galaxy. Cataloged in the early 20th century by astronomer E. E. Barnard, the obscuring interstellar dust clouds include B59, B72, B77 and B78, seen in against the starry background. Here, their combined shape suggests a pipe stem and bowl, and so the dark nebula’s popular name is the Pipe Nebula. The deep and expansive view covers a full 10 by 10 degree field in the pronounceable constellation Ophiuchus. The Pipe Nebula is part of the Ophiuchus dark cloud complex located at a distance of about 450 light-years. Dense cores of gas and dust within the Pipe Nebula are collapsing to form stars.

说明：在心宿二的东边，一片片黑色的印记在满布恒星的区域中向着银河系中心蔓延。在20世纪早期,天文学家E.E.巴纳德将这些模糊的星际尘云纳入了星表，其中包括B59, B72, B77 and B78。在星空背景的映衬下，我们才得以看到这几片黑色的星际尘云。图中，星际尘云合在一起，看起来像是一个烟斗柄和一个碗，烟斗星云因此而得名。这幅广域深空照片覆盖了位于蛇夫座的一块10平方度的天区。烟斗星云是蛇夫座暗云复合体的一部分，距离我们约450光年。烟斗星云内由气体和尘埃组成的稠密云核正在持续坍缩并形成恒星。
