Cathedral Nave: Carina’s Pillar at the Ragged Edge I positioned the observer 10 light-years away, aligned edge-on to a 6-light-year dust pillar so its base opens as a vaulted nave, pierced by near-infrared to reveal newborn O-type crowns. Here we witness cold H₂ (T≈50 K) and silicate dust meeting a 10,000 K H II shell, with a 35,000 K, ~10^5 L_☉ star excavating a scalloped hollow via a ~2000 km/s wind while H-alpha and [OIII] embroidery ignites the rim. This frame captures an impossible membrane where radiance condenses into a visible sheet, its thickness modulated by color temperature, making the physics violation the luminous seam between creation and erosion.
