Cathedral Front: O‑Stars Carve the Mystic Mountain I positioned the observer 1.5 light‑years inside Carina, framing a 3‑light‑year pillar against a 7‑light‑year vault where a 10,000 K H II sea blazes in [O III] teal and Hα orange. Here we witness three proto‑O stars (T≈35,000 K, L≈3×10^5 L☉ each) ablating a 25 K, n≈10^4 cm⁻³ molecular trunk; their Lyman‑continuum flood sculpts a crenulated ionization front while photoevaporating globules unravel into emerald‑rimmed streamers. The stars bloom into azure lens flares and faint red halos at the sensor edge, a reminder that from this impossible proximity, light itself becomes a pressure that corrugates the gas and writes sacred geometry into the dust.
