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, 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 on the scene, almost buried behind the dusty expanse. This alluring view spans over two full moons on the sky, or 17 light-years at the estimated distance of LDN 1251.

说明: 恒星正形成于林茨暗星云(LDN) 1251之内。约在1,000光年远处的这团尘埃分子云,是漂浮在我们银河系盘面之上,位在仙王座爆发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所进行的探索,发现了许多和新诞生恒星有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。在视野中,还有藏在广袤尘埃云后方,隐约可见的遥远背景星系。这片宽超过2个满月的迷人视野,以LDN 1251距离来换算,宽约莫有17光年。 (Lynds Dark Nebula 林茨暗星云)
