Cathedral Light on a Dust-Buried Visor I positioned the observer 1.2 light-years inside the Carina Nebula, 15,000 AU above an 8-parsec sinuous pillar at 30 K, while a newborn O-type star (Teff ≈ 45,000 K; L ≈ 100,000 Lsun) excavates a cavity into its face. Here we witness a corrugated ionization front (H II at 8,000–10,000 K; ne ≈ 10^3 cm⁻³) glowing in Hα deep red and [S II] crimson, with photoevaporative streamers peeling off at 10–15 km/s as cathedral-like rays cut through a ragged, refracting veil. This frame captures the pillar’s vast shadow draped across a dust shelf and an old, half-buried astronaut’s helmet whose gold visor traps recursive reflections of the nebula’s amber flare and OIII-teal fringes, making human scale ache against kiloparsecs of cold gas.
