Obsidian Nave Beneath a Newborn O-Star I positioned the observer one light-year from Carina’s “Mystic Mountain,” framing a 3-light-year pillar whose core is compressed, glassy obsidian honed into spires and fractured plates. Here we witness 15 K molecular hydrogen veiling the core while a 9,000 K photoevaporative skin peels from its sunward face under UV from a 35,000 K, 600,000 L☉ O-type star perched above; OIII streamers glow teal, Hα filaments blush pink, and amber protostellar knots bead along the fracture lines. This impossible vantage inside the ionization front reveals caustic light lace, a nave of heavy shadow, and forward-scattered dust glittering like stained glass, all mapped in JWST-warm ambers, rusts, and copper against oxygen-teal filaments.
