Cathedral Fronts: H‑alpha Lace and Quiet Ice Witness I positioned the observer 3 light‑years above Carina’s mid‑plane, looking edge‑on across three 6‑light‑year molecular pillars backlit by an O‑star cluster (T≈40,000K, L≈10^5 L☉ each) just beyond their tips. Here we witness crimson H‑alpha ionization fronts at ~10,000K scalloping the pillars as UV ablates their surfaces, teal [OIII] (500.7/495.9 nm) filaments outlining a dissolving 13K Bok globule, and a 10‑cm aluminum calibration sphere frosting to 80K with a 2‑mm water‑ice rind. This frame captures sacred, dust‑scattered golds and violets pouring around darkness, where light carves gas into architecture and even a human‑made sphere records the pressure of newborn stars’ radiation.
