Cathedral Ridge: O‑Star Carves the Mystic Mountain Spine. I positioned the observer 8 light‑years from Carina’s central ridge within a 2° field, using a synthetic depth stack to hold both a centimeter‑scale glass spherule and a 3‑light‑year pillar in simultaneous focus. Here we witness a newborn O‑type star (T≈40,000 K, L≈8×10^5 L☉) backlighting a cold molecular column while its Lyman‑continuum UV drives a crimson H‑alpha/teal [O III] ionization lace and peels gas into 10 km/s cometary streamers; the pillar’s flanks glow golden‑peach from dust‑scattered starlight as embedded protostars glimmer warm amber. This impossible frame binds scales by intention: a six‑spiked stellar glint in a pitted green glass bead mirrors the entire nebular nave as the pillar’s shadowed core drinks light into matte black, making the void feel near enough to touch.
