Cathedral Rim: O‑Star Baptizes Dust I positioned the observer 0.6 parsec from a six–light‑year molecular pillar, 4 light‑years inside the Carina Nebula, to look outward along its sunward face as a 38,000 K O‑type star (~4×10^5 L☉) blasts it with UV. Here we witness H‑alpha at 656 nm lighting a 10,000 K ionization rind while OIII (500.7 nm) eddies churn; photoevaporative flows peel away at ~10 km/s, and a Herbig–Haro microjet beads crimson along a carved channel. An impossible terrestrial mahogany pew sits level in the pillar’s shadow, its lacquer glint echoing as a blush along the rim—telescope‑quality clarity from within a place no telescope can go, where scale and silence overwhelm human measure.
