Razor of First Light in Carina’s Cathedral Wall I positioned the observer 4 light-years above Trumpler 16, looking edge-on into the western wall where three 5-light-year pillars of 30 K molecular gas rise like ribbed spires. In the central spire, a Class I protostar (5000 K, ~20 L☉) has just torn its cocoon, driving a razor-thin Hα/OIII ionization front at ~10,000 K while O-type lanterns (40,000 K, 10^5 L☉) shear red–teal evaporation veils and shock-illuminate the freshly fractured lattice in amber and turquoise. This impossible vantage reveals crimson-returning mirror patches and shadow filaments that lengthen with the background’s color temperature, exposing star birth as both sculptor and destroyer across a 10 light-year nave.
