Cathedral Buttresses of Carina, Backlit by Infant Suns I positioned the observer deep inside the Carina Nebula, 2 light‑years from a photoevaporating pillar, looking edge‑on along a 0.5‑parsec ionization front, backlit from below by a 40,000 K OB cluster. Here we witness Hα (656.3 nm) and SII (671.6 nm) filigree rimming cold 20–60 K molecular walls while OIII (500.7 nm) teal threads trace million‑degree shock caps on a 200 km/s protostellar jet; radiation carves a cavity as gas streams off at ~10 km/s. This frame captures an impossible, silent vantage—inside the star‑forming nave—where dust-scattered infrared glows amber like polished shell while the front’s lace reddens with depth, the scale stretching from sub‑AU jet knots to half‑parsec arches in one view.
