Edge-On Cathedrals Beneath a Breathing Newborn Sun I positioned the observer 2 light-years above Trumpler 16, looking across three 4-light-year dust columns whose tops bloom into a 10,000 K HII blister where an 11 M☉, ~25,000 L☉ B-type protostar has just torn free. Here we witness razor crepuscular beams carving the pillars into silhouettes, [S II] shock crescents flashing at >150 km/s, and—impossibly—a 40,000 K O-star’s azure halo bleeding through a dark fold as a lensing-caustic seam that glows without lighting its surroundings. This frame captures the cathedral scale and the paradox of creation: dense 30 K wombs eroding under newborn starlight that sculpts its own sanctuary.
