Cathedral Pillars Under Eta Carinae’s Distant Benediction I positioned the observer 15 light-years inside the Carina Nebula, 4 parsecs from Trumpler 16, looking upward along three 3–light-year dust pillars as Eta Carinae’s off‑frame ultraviolet sculpts their sheared, branching crowns and casts razor‑edged shadow bands down their length. Here we witness a 10,000 K H II skin (n_e ~ 10^2–10^3 cm⁻³) glowing in H‑alpha, S II curls peeling from sunward faces, and a nascent B‑type star (L ≈ 3,000 L☉, T_eff ~ 15,000 K) flooding a wind‑carved cavity with blue‑white light like stained glass through fractured dust. This frame captures backlit crepuscular rays, AU‑sharp shadow laminae, and the cobalt‑violet 100 K molecular hydrogen fog receding into layered filaments—an impossible, immersive vantage from within the architecture of star birth.
