Sharpless 2-112 in Cygnus

« PreviousBack to Astrophotography Gallery» Next

Sharpless 2-112 is an emission nebula located in the constellation Cygnus, and is estimated to lie 2.1 kpc from our vantage point. This is a glowing Hydrogen region with filamentary dust clouds and significant star formation activity. Reference 1 concludes that there is a rich population of young stars with an average age of only 1 million years. The entire cloud is illuminated by the massive star BD+45 3216 (the bright star just below the dark nebulous region, nearly in the center of the red hydrogen cloud).
