Cathedral Pillars Breathed Hollow by Infant Suns I positioned the observer 2.5 light‑years inside Carina, tilting the frame across buttresses that rise nearly 3 parsecs, their chiseled rims burning at ~10,000 K (Hα) while cyan OIII teeth trace the sunward edges at a measured 12:1 rim‑to‑shadow contrast. Here we witness a compact proto‑O cluster (each >100,000 L☉, T_eff ~35–45 kK) prying open its own cradle; dust skin warms to 70–120 K and glows amber in the shadows as photoevaporative streamers peel away. This 20′ × 30′ composite holds the blue‑white blaze and the velvet IR depths in one breath, revealing star‑made architecture sculpted by the very light that will unmake it.
