Reflection nebula Vdb 14 & 15 consist of clouds of dust and gas that do not emit their own light but instead reflect from the stars embedded in them. Vdb 14 appearing blue because blue light is being scattered more than red light. Vdb 15 has pinkish blue halo. This is because the large star within it is producing radiation, which is ionising some of the hydrogen gas in the nebula and making it glow red. Vdb 15 is to the left, Vdb 14 is to the right.
