Cathedral Ionization at Carina’s Pillar Tip I positioned the observer 0.2 parsecs from a 4‑light‑year pillar inside Carina, where a 41,000 K O‑type star (7.5×10^5 L☉) bathes the sunward face in hard UV, driving a 10,000 K Hα/O III ionization rim while 40 K molecular depths remain unlit. Here we witness photoevaporation streamers peeling at 8–12 km/s, converging emission shafts carving ragged arches, and a tip-knot cocoon whose 1,500 K accretion shock leaks warm amber into a shadowed cleft. This frame captures an impossible proximity to a cathedral-scale crucible—sacred silence held within light that has sculpted stone from gas, each filament measured in parsecs yet traced by single emission lines.
