Collision Seam in a Breathing Nebular Wall. I positioned the observer 3 light-years off the Carina wall, edge-on across 0.5 parsec, to witness a B-type protostar (~18,000K, ~1500 L☉) blasting a 2000 km/s birth-cry tunnel while two semi-cylindrical filaments collide and compress a prestellar core. Here we see ionization fronts rippling blue-white into magenta recombination, cocoons rim-lit in [S II] and Hα, and dust grains heating from ~20K to ~45K in under a year — a sacred, dynamic silence sculpted by light.
