Cathedral Edge: Light Carves Carina’s Mystic Mountain I positioned the observer 0.15 parsecs above the pillar tip, 6 light-years inside Carina’s southeastern vault to witness three infant O-type stars (surface T≈38,000 K, absolute magnitude ≈−6) ionizing the 30 K molecular pillar skin where shadow meets light. Here the bow-shaped shock at 12,000 K chews the tip globule as H-alpha (deep carmine) and OIII (turquoise) rims ignite along fingered edges; supersonic winds pull dust into warm-gold streamers that veil the scene. This intimate macro frame reveals the impossible: a UV caustic pane that makes the ionization boundary glow like stained glass, while time-shear ripples ghost the shock—starfire sculpting its own sanctuary at parsec scale.
