LBN 337 (aka: Sharpless 2-112) is a star forming region located in the constellation of Cygnus. The nebulas red glow is caused by the bright star BD+45 3216 located center near the thick optical absorbing molecular cloud. Much of the light from this class 08V star is emitted in the ultraviolet range and is causing the surrounding gasses to glow with a blue hue. The size of this star is approximately 30 times that of our Sun and its stellar winds are eroding the H II regions. The glowing gasses within the dark lanes are where other stars are forming.
