在遙遠的宇宙中，有一個神秘的地方叫做Lynds’ Dark Nebula (LDN) 1622。這裡像是一片黑暗的天空，背後隱藏著微弱的氫氣，在用望遠鏡仔細觀察時才能看見。就在這個黑暗的星雲上方，有一個亮亮的星雲叫做vdB 62，容易被發現哦！LDN 1622位於我們的銀河系中，與Barnard’s Loop這個大雲相近，Barnard’s Loop是圍繞著很多美麗的星雲的。一些年輕的恆星就藏在這片黑暗的星雲裡，透過斯皮策太空望遠鏡的紅外線影像，我們能看到它們的身影。不過，這片名叫Boogeyman Nebula的星雲，讓人一看就感到神秘又有點害怕呢！

The silhouette of an intriguing dark nebula inhabits this cosmic scene. Lynds’ Dark Nebula (LDN) 1622 appears against a faint background of glowing hydrogen gas only visible in long telescopic exposures of the region. In contrast, a brighter reflection nebula, vdB 62, is more easily seen just above the dusty dark nebula. LDN 1622 lies near the plane of our Milky Way Galaxy, close on the sky to Barnard’s Loop, a large cloud surrounding the rich complex of emission nebulae found in the Belt and Sword of Orion. With swept-back outlines, the obscuring dust of LDN 1622 is thought to lie at a similar distance, perhaps 1,500 light-years away. At that distance, this 3 degree wide field of view would span about 100 light-years. Young stars do lie hidden within the dark expanse and have been revealed in Spitzer Space telescope infrared images. Still, the foreboding visual appearance of LDN 1622 inspires its popular name, the Boogeyman Nebula.
