Cathedral Edge at Mystic Mountain’s Ionized Tip I positioned the observer 0.15 parsecs above the pillar’s apex, six light-years inside Carina’s southeastern wall, to look down the sunward face of an 18-trillion-kilometer molecular column. Here we witness three O-type stars (T_eff ≈ 38,000 K, M_abs ≈ −6) driving ~2000 km/s winds and hard UV that skin the 30 K pillar; the quantum-thin boundary fluoresces H‑alpha carmine and OIII turquoise while a 12,000 K bow shock bites into a dense globule, ejecting ablated beads at tens of km/s. This frame captures dust veils forward‑scattering starfire to warm gold, embryo protostars glowing in the infrared, and raking illumination that turns star birth into stained glass at cathedral scale.
