Cathedral Fire along the Mystic Mountain's Edge I positioned the observer 3 light-years from Carina’s central cluster to hold the 3‑light‑year-tall “Mystic Mountain” in profile while a newborn O‑type star (T≈38,000 K) flays its flank at 0.01 parsecs per century. Here we witness crisp O III (500.7 nm) teal filaments edged by Hα (656.3 nm) magenta riding a cold 20 K dust spine, as a parsec-long HH jet barrels out at ~250 km/s, its 10,000 K bow compressing gas into scalloped arcs. This frame captures an Hubble SHO exposure—gold dust, aqua oxygen, crimson sulfur—where even a time-shifted light echo on a thin dust sheet writes a reflection that moves on its own.
