vdB 123¹, as designated in the van den Bergh catalog², is a blue reflection nebula⁷ located in the constellation Serpens approximately 800 light years (230 +/- 20 parsecs)³ from the Earth. This colorful nebula is embedded in a large cloud of dust and gas known as the Serpens Cloud³. This cloud overlays a rich field of background Milky Way stars. These background stars appear to be heavily “reddened” by the cloud’s intervening dust. A large dark nebula extending throughout the region is cataloged Dobashi 1260^5,6. These areas of dense dust obscures background stars and other celestial objects. The bright blue central nebula shines from light reflected from the bright star designed HD 170634¹. The blue color is a result of the surrounding dust reflecting the shorter wavelengths of light more efficiently than longer wavelengths. This is essentially the same phenomena that makes our Earthly sky appear blue.
