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 telescopic frame spans almost three full moons on the sky. That corresponds to over 25 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）之内。漂浮在我们银河系盘面上方的LDN 1251，有个令人倒胃口的臭鱼星云（Rotten Fish Nebula）之昵称。而位于仙王爆发区方向的这团尘埃分子云，也是距离我们约1,000光年远的暗星云复合体之一部分。在各个电磁波段对这个黝黑星际尘埃云所进行的探索，发现了许多和新诞生恒星相关的高能激波和外泛流，包括散布在这张影像里的特征性泛红赫比格-哈罗天体。此外，视野里还可见到藏在广袤尘埃云后方、隐约可见的遥远背景星系。这幅迷人的望远镜视野，大约涵盖了3个满月的天空，以LDN 1251的估计距离来换算，其宽度约有25光年。
