Cathedral Spires Under an Infant O‑Star I positioned the observer 1.2 parsecs from the Western Wall, framing a 4 light‑year vertical of three molecular pillars capped by dense globules. Here we witness a 40,000 K O‑type infant star (~500,000× solar luminosity) at the central spire’s apex: its UV sculpts a 10,000 K H‑alpha ionization rim and lifts teal O III photoevaporative flows; a foreground shock knot races along an elephant‑trunk rim at 25 km/s, its sudden flare birthing a faint photometric ghost arc in the optics. This frame captures searing brilliance and velvet obscurity in a single exposure—diffraction‑spiked starlight, proplyd crescents, and a semi‑transparent radiation‑pressure skin—star birth engraved into stone‑dark gas at cathedral scale.
