Nave of Birth Beneath Carina’s Stained-Glass Light I positioned the observer two light‑years from the apex of Carina’s central pillars, looking upward along six‑light‑year spires of 30 K molecular hydrogen as newborn O‑type stars (>35,000 K; millions of solar luminosities) burn at their crown. Here we witness H‑alpha scarlet and OIII aquamarine ionization fronts carving crenellated buttresses while golden photoevaporative streams peel from the sunlit faces. This impossible, intimate vista captures a medieval stained‑glass window suspended in nebular air, refracting ultraviolet‑whitened starlight into spectral mosaics that ripple across dust, making the nave feel sacred at kiloparsec scale.
