Reflection Nebulae in Orion

This image features the reflection-nebula complex surrounding Messier 78 (M78 / NGC 2068), along with NGC 2064, NGC 2067, and NGC 2071, all embedded within the Orion molecular cloud environment.

Unlike emission nebulae, these objects shine primarily by scattering and reflecting starlight off interstellar dust, producing the characteristic bluish glow of reflection nebulae.
