       Discover the cosmos! Each day a different image or photograph of our   
         fascinating universe is featured, along with a brief explanation

                          LDN 1622: Dark Nebula in Orion

      Explanation: 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.
