Stars are forming in dark, dusty molecular cloud LDN 988. Seen near picture center some 2,000 light-years distant, LDN 988 and other nearby dark nebulae were cataloged by Beverly T. Lynds in 1962 using Palomar Observatory Sky Survey plates. Narrowband and near-infrared explorations of the dark nebula reveal energetic shocks and outflows light-years across associated with dozens of newborn stars. But in this sharp optical telescopic view, the irregular outlines of LDN 988 and friends look like dancing stick figures eclipsing the rich starfields of the constellation Cygnus. From dark sky sites the region can be identified by eye alone. It’s part of the Great Rift of dark nebulae along the plane of the Milky Way galaxy known as the Northern Coalsack.

在黑暗多塵的分子雲 LDN 988 中，星星正在形成。此區域位於圖片中央，距離地球約 2,000 光年，LDN 988 及其他附近的暗星雲由 Beverly T. Lynds 於 1962 年利用帕洛瑪天文台的天圖進行編目。使用窄帶和近紅外探索的結果顯示，與數十顆新生星星相關的能量衝擊和物質流在光年之內展開。在這幅銳利的光學望遠鏡視圖中，LDN 988 及其夥伴的不規則輪廓彷彿是跳舞的火柴人，穿越著豐富的星空，位於天鵝座的星群中。在黑暗的天空地點，這個區域甚至可以憑肉眼辨認出來。它是沿著銀河系的平面被稱為北方煤袋的暗星雲大裂縫的一部分。
