A photorealistic street art mural of a massive snowy owl with pristine white plumage and golden eyes perched on the broken telescope platform of an abandoned astronomical observatory, its feathered texture rendered in hyperrealistic spray paint with individual barb details and luminous glow, cold starlight streaming through shattered dome casting silver beams across scattered astronomical charts and toppled equipment, mood cosmic and wise yet lonely, composition centered with owl overlooking the industrial space, broken star maps and fallen telescope lenses creating scientific decay, color palette pristine whites and deep blacks contrasted with cool steel grays and soft celestial starlight
