Explanation: The prominent ridge of emission featured in this vivid skyscape is designated IC 5067. Part of a larger emission region with a distinctive shape, popularly called The Pelican Nebula, the ridge spans about 10 light-years and follows the curve of the cosmic pelican's head and neck. Fantastic, dark shapes inhabiting the view are clouds of cool gas and dust sculpted by energetic radiation from young, hot, massive stars. But stars are also forming within the dark shapes. Twin jets emerging from the tip of the long, dark tendril left of center are the telltale signs of an embedded protostar cataloged as Herbig-Haro 555 (HH 555). In fact, other Herbig-Haro objects indicating the presence of protostars are found within the frame. The Pelican Nebula itself, also known as IC 5070, is about 2,000 light-years away. To find it, look northeast of bright star Deneb in the high flying constellation Cygnus.

说明:这个生动的天空 特征的突出的发射脊 被指定为IC 5067.具有独特形状的较大发射区域的一部分,通常称为 鹈鹕星云,脊跨过约10光年,并遵循宇宙鹈鹕的曲线头颈部 梦幻般的,黑暗的形状居住在这个景观上,是由来自年轻,热的,巨大的恒星的精力充沛的辐射雕刻出的气体和灰尘的云彩 。但星星也在黑暗的形状内形成。从中心左边长长的黑色卷须尖端出来的双筒喷射机是被描述为Herbig-Haro 555(HH 555)的嵌入式原型星的标志符号。 其实, 指示存在原始体的 其他Herbig-Haro对象位于框架内。鹈鹕星云本身也称为IC 5070,距离大约2,000光年。 要找到它,在高星座天鹅座的明星明星Deneb的东北方向看 。
