怪异的形状似乎萦绕在这片尘埃漫天的天空中，飘过夜晚的仙王座。当然，这些形状是在暗淡的星光反射下可见的宇宙尘埃云。它们远离你的邻居，潜伏在离我们1200光年远的仙王座耀斑分子云复合体的银河系平面上方。vdB 141或Sh2-136直径超过2光年，比大多数其他幽灵更亮，也被称为幽灵星云，位于星空的右侧。在星云内部，密集的核心在恒星形成的早期阶段坍塌的迹象。伴随着怪异的尘埃色调反射着NGC 7023中炙热的年轻恒星发出的蓝光，虹膜星云在中间偏左的黑暗中脱颖而出。在广阔的望远镜框架中，这些肥沃的星际尘埃区几乎延伸了七个满月穿过天空。

Spooky shapes seem to haunt this dusty expanse, drifting through the night in the royal constellation Cepheus. Of course, the shapes are cosmic dust clouds visible in dimly reflected starlight. Far from your own neighborhood, they lurk above the plane of the Milky Way at the edge of the Cepheus Flare molecular cloud complex some 1,200 light-years away. Over 2 light-years across and brighter than most of the other ghostly apparitions, vdB 141 or Sh2-136 is also known as the Ghost Nebula, seen at the right of the starry field of view. Inside the nebula are the telltale signs of dense cores collapsing in the early stages of star formation. With the eerie hue of dust reflecting bluish light from hot young stars of NGC 7023, the Iris Nebula stands out against the dark just left of center. In the broad telescopic frame, these fertile interstellar dust fields stretch almost seven full moons across the sky.
