3rd Annual Air & Space Photo Contest
The glow of the Iris Nebula

Proudly displaying its trademark blue likeness, the Iris Nebula owes its appearance to the reflection of a central cluster of stars (NGC7023) against a set of interstellar dust that sits roughly 1,300 light years from Earth. Additional clouds sitting further from the center of the reflection nebula are too distant from the star cluster for illumination, resulting in thick, opaque areas that block the light of stars beyond the nebula.
