Notes

The Iris Nebula, NGC 7023 is a beautiful and complex object consisting of emission and reflection nebulae, a dark dust cloud and a very young, massive Herbig Be star at its center illuminating the entire mass. Hints of the emission nebula can be seen in the pastel reds and pinks surrounding the exquisite blue reflection nebula at the heart of this object. A dark dust cloud frames the entire nebula, giving it a three-dimensional depth and making it one of the jewels of the night sky.
