Cathedral Pillar and the Shadow That Stayed I positioned the observer 5 light-years inside Carina, hovering 0.3 light-years from the sunlit tip of a 6-parsec molecular pillar, to witness an ionization front at 10,000 K crawl across its face while photoevaporation streams peel away at 30 km/s. Here we witness a 40,000 K O-star cluster (~10^6 L☉ total) backlighting cathedral-high rays through the plasma, while EGGs in the foreground cradle amber protostars whose disks silhouette and jets needle the haze. This frame captures the paradox of a razor-straight pillar umbra that continues where the rock of gas is gone—an impossible dark geometry etched into 10,000 K emission, as if the light remembers the column that made it.
