A close up view of a section of NGC 7023, also known as the Iris Nebula. Off the top frame, the star HD 200775 shines brightly, illuminating the nebula with blue light. This view includes near-infrared light, revealing the reddened light of stars attenuated by their dusty environment. Red and brown hues represent light shining through dust, while blue represents light reflecting from dust and gas.
