说明:恒星正在林茨暗星云(LDN)1251中形成。这片尘埃分子云距离我们约1000光年,漂浮在我们银河系的平面之上,是一个复杂的暗星云的一部分,它被映射到仙王座耀斑区域。在整个光谱中,对模糊星际云的天文探索揭示了与新生恒星相关的能量冲击和外流,包括这张清晰图像中可见的分散的赫比格-哈罗天体发出的暗红色辉光。遥远的背景星系也潜伏在这一场景中,视觉上隐藏在尘土飞扬的广阔区域后面。用宽频带滤光片拍摄的深望远镜视野覆盖了大约两个满月的天空,在LDN 1251的估计距离上是17光年。

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 seen in this sharp image. Distant background galaxies also lurk on the scene, visually buried behind the dusty expanse. The deep telescopic field of view imaged with broadband filters spans about two full moons on the sky, or 17 light-years at the estimated distance of LDN 1251.
