Cathedral Gate: Three O‑Stars Above a Shadowed Pillar. I positioned the observer five light-years deep inside Carina’s “Mystic Mountain,” looking upward from the cold face of a molecular buttress as three 40,000 K protostars ignite a ragged summit cavity. Here we witness H‑alpha jets (656.3 nm) boring crimson veins through dust while a 8,000–12,000 K ionization front curls and recedes, revealing teal O III lace beyond; the exposure rides the dynamic range so UV-grazed rims burn electric while sheltered flanks fall into velvet shadow. This frame captures radiation pressure peeling material at tens of km/s, casting moving caustics from glittering grain-skims onto a sky-filling vault—an impossible, embedded vantage no telescope could occupy without erasing the very dust that sculpts the light.
