At a distance of 1000 light years, the nebula is the closest HII region to us , a star formation region . The cloud is presumably stimulated to glow by the nearby star ξ Persei .
Because of its low surface brightness , the shape of the nebula can only be seen on long-exposure photos. It can only be seen with the naked eye on very dark nights.
