Erosion Liturgy at Carina’s Western Pillar I positioned the observer 4 light-years from the pillar’s tip, looking up along a 5-light-year wall of 30 K molecular gas as a 45,000 K O-type star (≈5×10^5 L☉) at 0.3 light-years scours it. Here we witness Hα and [SII] reds interlaced with [OIII] aquamarine where the 10,000 K ionization front advances ≈0.01 light-years per century, peeling dark dust into bright streamers. This frame captures the sacred violence of photoevaporation in long-exposure optical/NIR, the blue-white star backlighting scalloped rims while embedded protostars glimmer as faint gold at A_V>10, a cathedral dissolving as it reveals its makers.
