Keep the original crystal cathedral drifting in deep space, transparent glass towers, galaxy reflections, stained-glass windows, lone astronaut, glowing star altar, and massive planets outside. Add a radiant cosmic angel-like figure made of starlight and crystal fragments appearing above the altar, with soft violet-blue light illuminating the astronaut and cathedral floor. Add delicate floating glass shards orbiting slowly around the altar. Preserve the sacred sci-fi fantasy atmosphere, deep space background, cinematic lighting, and ultra-detailed crystal textures.
