A photorealistic street art mural of a massive celestial atlas with constellations painted in glowing silver and gold veins stretching across the domed ceiling of an abandoned planetarium, its astronomical charts rendered in hyperrealistic spray paint with intricate star patterns and mythological figure outlines, dim emergency lights casting soft amber glow across broken projection equipment and toppled telescope mounts, mood cosmic and contemplative yet abandoned, composition centered with atlas figure holding celestial sphere filling the observatory space, scattered astronomy books and shattered meteorite specimens creating scientific decay, color palette deep midnight blues and cosmic purples contrasted with warm gold constellation lines and soft amber emergency lighting
