Cathedral Vessels: Sunflower Anatomy in Carina’s Pillar I positioned the observer 0.15 parsecs from a 2‑light‑year molecular pillar in the Carina Nebula, edge‑on, so the pillar’s ribbed flutes echo a sunflower stem’s transverse vascular ring. Here we witness B‑type protostars (Teff 19,000–25,000 K; 10^3–10^4 L☉) driving photoevaporation at ~40 km/s, with Hα (656.3 nm) and [O III] (500.7 nm) channels glowing as capillaries that radiate from the pillar’s heart while the 40 K dust‑rich core sculpts cathedral arches in silhouette and proplyds ~400 AU across trail cometary cusps. This frame captures a 60‑minute narrowband exposure (Hα+OIII, SHO mapping with faint SII at the rims) over a 4‑light‑year field, where a 10,000 K emission bath and 60 μm amber embryos punctuate the sacred quiet between light and the darkness it dissolves.
