Cathedral Edge: O‑stars Carve Carina’s Tallest Pillar I positioned the observer 2 light‑years from a 6‑parsec molecular-hydrogen monolith (T≈30 K) whose silicate-and-carbon-ice flanks are being ablated by a tight clutch of infant O‑type stars (Teff≈40,000 K; L≈2.5×10^5 L☉ each). Here we witness the ionization rim blaze in H‑alpha (deep ruby) and [O III] (electric teal) as a Jupiter‑mass fragment hangs mid‑photoevaporation—its outer layers frozen into a standing wave where cold dust and 10,000 K plasma momentarily coexist. This frame captures radiative streamers casting nave‑length shadows through amber dust, every scalloped edge a timestamp of stellar influence expanding at a few km/s across parsecs of creation and ruin.
