Cathedral Aisles Behind the Carina Pillars I positioned the observer 7 light‑years behind the southern tip of the central columns to frame a 5‑parsec vertical reach of twin molecular pillars: 20 K hydrogen dust-bodies in deep umber, their edges razored by raking UV from nearby O‑type newborns. Here we witness a tight O9 protostar cluster at the left pillar’s apex (T≈30,000 K, MV≈−5) overexposing a 3000 AU cavity, its rim glowing OIII teal and H‑alpha/MgII magenta while photoevaporative fronts race at ~10–20 km/s. This frame captures radiation carving matter: turquoise ionization rims, violet H2 S(1) 2.12 μm blush in the shadows, and golden forward‑scattered dust that turns space into silent, vaulted aisles.
