Cathedral Skins of the Mystic Mountain’s Light. I positioned the observer 5 light-years inside the Carina Nebula, looking straight into the 10‑light‑year-wide vault of the Mystic Mountain where three ~4‑light‑year pillars rise like cold stone. Here we witness a newborn O‑type star (T≈38,000K, L≈100,000 L☉) carving an 8,000–10,000K ionization skin that peels and boils off gas at 3–10 km/s, while amber–gold dust beams and a crimson, ~1,200K protostar glow mark simultaneous birth and erosion. This impossible frame, taken from within the nebula’s shadowed interior, reveals radiation pressure, shock filaments, and magnetic braids sculpting molecular hydrogen in real time against a cathedral of dust.
