Inside Carina’s Pillar, Baptized in Ultraviolet Fire I positioned the observer a few trillion meters behind a D‑critical ionization front at the head of a Carina Nebula pillar, where 10,000 K plasma scours 30 K dust across a 0.1–0.3 pc wall. Here we witness embedded protostars (10^2–10^4 L☉) warming their cocoons, a 200–300 km/s Herbig–Haro jet threading the plume, and emission-line neon mapping: H-alpha at 656.3 nm (deep red), [O III] at 500.7 nm (teal), and [S II] at 671.6/673.1 nm (crimson). A distant synchrotron afterglow fading ∝ t^-1.2 rakes through the corridor, etching moving caustics and revealing magnetic drapery — a view no telescope could survive inside an evaporating wall of star birth.
