It is a reflectionnebula, caused by dust reflecting the blue light of the hot, young stars. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Images in the infrared show a bright young stellar object, with an associated reflectionnebula seen as a glowing cone projecting from the young star. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. It produces a bright visual reflectionnebula and an ultraviolet-excited photodissociation region. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The smaller reflectionnebula component requires a larger instrument and averted vision to be seen.

These objects are likely protostellar in nature, with the excess radiation at long wavelengths caused by suppression by the reflectionnebula in which the protostars are embedded.

From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Reflection nebulae and emission nebulae are often seen together and are sometimes both referred to as diffuse nebulae. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Thus, the frequency spectrum shown by reflection nebulae is similar to that of the illuminating stars. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. In visible light these nebulae may be further divided into emission and reflection nebulae. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Reflection nebulae are usually blue because the scattering is more efficient for blue light than red (this is the same scattering process that gives us blue skies and red sunsets). From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Reflection nebulae are actually made up of very fine dust that normally appears dark but can look quite blue when reflecting the light of energetic nearby stars. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The scattering of light from dust grains in long exposure visible photographs is quite noticeable in reflection nebulae, and gives clues about the individual particle's light-scattering properties. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Some 500 reflection nebulae are known.
