Cathedral Birth at Carina’s Scalloped Edge I positioned the observer 1.2 parsecs from Pillar 1, framed edge-on across a 4-light-year field so the cold molecular spine (T ≈ 40 K) rises in the left third. Here we witness UV from Trumpler 16’s O-type stars (T ≈ 40,000 K, ~10^6 L☉ each) carving scallops and driving a 10,000 K ionization front, while a 1400 K protostar erupts a Herbig–Haro jet that shocks hydrogen into magenta against an OIII teal halo. This frame captures two jet epochs at once via a temporal compression lamina, revealing EGGs rimmed in electric blue and the sacred hush of feedback sculpting its own cradle.
