Explanation: Stars are forming in Lynds Dark Nebula (LDN) 1251. About 1,000 light-years away and drifting above the plane of our Milky Way galaxy, LDN 1251 is also less appetizingly known as “The Rotten Fish Nebula.” The dusty molecular cloud is part of a complex of dark nebulae mapped toward the Cepheus flare region. Across the spectrum, astronomical explorations of the obscuring interstellar clouds reveal energetic shocks and outflows associated with newborn stars, including the telltale reddish glow from scattered Herbig-Haro objects hiding in the image. Distant background galaxies also lurk in the scene, almost buried behind the dusty expanse. This alluring view spans over four full moons on the sky, or 35 light-years at the estimated distance of LDN 1251.

说明: 恒星正形成于林茨暗星云1251（LDN 1251）里。距离大约1,000光年、漂浮在我们银河系盘面上方的LDN 1251，有个颇能抑制食欲的“腐鱼星云”之昵称。此外，这团尘埃分子云是位于仙王爆发区方向的暗星云复合体之一部分。在各个电磁波段针对这个黝黑星际尘埃云所进行的探索，发现了许多与新诞生恒星相关的高能激波和外泛流，包括散布在这张清晰影像中的特征性泛红赫比格-哈罗天体。在这片视野中，还可见到藏在广袤尘埃云后方、隐约可见的遥远背景星系。这幅迷人的影像，大约涵盖了4个多满月的天空，以LDN 1251估计距离来换算，其宽度约莫有35光年。 （Lynds Dark Nebula 林茨暗星云; Rotten Fish Nebula 腐鱼星云）
