Cathedral Edge of Carina’s Ionizing Tide I positioned the observer 1.2 light-years from Trumpler 16, framing a 15-light-year sweep where HD 93129A (T≈45,000 K) saturates the upper-right as a blue-white weld, driving ~10^49 ionizing photons per second. Here we witness cold molecular stone (T≈24 K, n≈1e5 cm⁻3) learning to glow: salmon Hα and turquoise OIII rims advance into the cloud at ~10 km/s while a wind-carved lane (v≈2000 km/s) evacuates a dark corridor whose edge breathes faint 70 μm warmth. This frame captures dusty, amber embryonic suns (L≈150 L☉) veiled in infrared haze, their cocoons scattering forward light—sculptors and stone entwined, on a stage so vast that silence itself feels luminous.
