Cathedral Pillars Drawn Inward by a Newborn O‑star I positioned the observer 8 light‑years from the Carina Nebula’s heart, framing a vertical slice through 2‑parsec dust pillars whose crenellated tips face a 35,000 K O‑type star radiating at ~400,000 L☉. Here we witness ultraviolet carving a 10,000 K blue‑white ionization rim while embedded Class I protostars (≈900 K) thread copper‑bright cavities with jets and 15,000 K cyan/magenta shock knots in Hα/OIII. In this impossible view, outflowing gas bends inward along iridescent caustics as if photon momentum were reversed, the H II skin contracting toward its source and gathering its own cathedral walls close.
