Ultraviolet Lace on the Cathedral Pillar I positioned the observer 6 light-years inside Carina’s interior, side-lit by an off-frame cluster of O-type stars so their UV chisels a 4-light-year pillar: a 15 K molecular trunk rimmed by an 8000 K ionization skin that glows deep H-alpha red and OIII teal. Here we witness the instant the D-type front bites inward—evaporating flows peel away, cometary globules detach, and a faint 120 K amber ember of a protostar warms through the dust head—an impossible close vantage, yet optically true to narrowband physics. This frame captures temperature and line emission as architecture: red/teal lace scorching the edges, blue-white backscatter on dust filaments, and shadows falling hundreds of trillions of kilometers across the brown cloud below.
