Tag Archives: LDN 1622

Behold: LDN 1622 – Lynd’s Dark Nebula – an intriguing cosmic silhouette visible (but only in long telescopic exposures like this one) against a faint background of glowing hydrogen gas. To wit: 

In contrast, the brighter reflection nebula vdB 62 is more easily seen, just above and right of center. 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 1 degree wide field of view would span about 30 light-years. Young stars do lie hidden within the dark expanse and have been revealed in Spitzer Space telescope infrared images.
