UV Cathedral: Mystic Mountain Under Stellar Baptism I positioned the observer 4 light-years from Carina’s core, facing the 3‑light‑year Mystic Mountain where 20–40 K molecular hydrogen resists a ~10^50 s⁻¹ UV photon storm from ten O‑type suns. Here we witness 10,000 K H II rims (H‑alpha 656.3 nm, [O III] 500.7 nm) lacing the pillar while a ~250 km/s Herbig–Haro jet punches a scalloped cavity that glows like hammered metal. This frame captures apricot‑amber IR reflection off sub‑micron silicate dust, three protostellar cocoons accreting ~10⁻⁶ M☉/yr, and a blue‑white overexposed quadrant where stellar winds open the void.
