A Dusty Iris #Nebula
The Iris Nebula (NGC 7023), 1,300 light-years away in Cepheus, is a star-forming region surrounded by dust and gas. Its blue hue comes from dust reflecting starlight, with red-tinted filaments glowing due to UV radiation. Spanning over 30 light-years, it may contain complex carbon molecules.
