Reflection nebulae reflect the light of stars that are located in their vicinity. They usually appear blue and often have diffuse, blurry shapes.
The Canadian astronomer Sidney van den Bergh published a catalog of reflection nebulae in 1966, known as the vdB catalog. The objects in this category are exclusively sorted by their number in the vdB catalog.
