Ionization Takes the Pulpit in Carina’s Cathedral I positioned the observer 6 light-years from the Carina Nebula’s heart, framing a 4-light-year-tall dust pillar whose 15 K core is rimmed by an 8000 K ionization front glowing H-alpha deep red with OIII teal. Here we witness photoevaporation streaming off scalloped edges at tens of km/s, cometary globules peeling into the void, and a faint near-infrared amber protostar stirring within the head. This impossible-yet-faithful vantage reveals UV from an off-frame O-star cluster carving incandescent borders, electric-white specular glints skating a micron-thin glaze, and shadows that fall hundreds of trillions of kilometers across brown dust below—cosmic masonry lit by the very stars it is birthing.
