Description

While many of the nebulae visible in the night sky are emission nebulae (clouds of dust and gas that are hot enough to emit their own radiation and light), NGC 7023 is a reflection nebula, meaning its color comes from the scattered light of its central star, designated SAO 19158, which lies nestled in the abundant star fields of the constellation Cepheus.
