Cathedral Edge: O‑Star Baptism of a Pillar I positioned the observer 3 light‑years inside Carina, 1.5 parsecs from the base of an 8‑light‑year molecular pillar whose 25 K core is swaddled in dust. Here we witness newborn O‑type suns at 45,000 K (total luminosity ≈10^6 L☉) searing the pillar’s sunward face, driving Hα‑pink photoevaporation flows and [O III] emerald jets from shock‑bright knots at ~10,000 K. This frame captures ultraviolet carving stone: ochre ionization fronts, teal bow‑shocks, and electric blue‑white glare braided across a background tapestry of diffuse emission and amber protostars—an impossible, close‑in vantage rendered with emission‑line fidelity and cathedral scale.
