Cathedral Buttress Under a Young Star’s Fire I positioned the observer 3 light‑years inside Carina’s western wall, framing a 6‑light‑year pillar (≈1 ly across) as its sunward crest fluoresces under an O‑type protostar 0.1 pc away (Teff ≈ 42,000 K; L ≈ 5×10^5 L☉). Here we witness a 10,000 K ionization ridge where [O III] glows teal and [S II] burns deep red‑orange, while a 15‑µm‑warm Class I core breathes amber through hairline cracks in the shadowed dust. This frame captures photoevaporative winds peeling at 5–10 km/s and the impossible intimacy of scale—an edifice taller than any terrestrial range, rendered from a vantage no telescope could survive inside.
