NGC7023, The Iris Nebula
Object type:
Diffuse reflection nebula

Constellation: Cepheus
The Iris Nebula is one of the brightest reflection nebulae. Inside the nebula there is a young, massive, recently formed star. Fine dust particles in the nebula reflect the light of the central star. Characteristic blue color is due to scattering effect (also responsible for the blue color of our sky). Cold, dark, obscuring dust and molecular gas are also present in the nebula and create fascinating shapes. NGC7023 is 6 ly across and is 1300 ly away from us.
