Cathedral Pillar Lit by an Infant O-Star Choir I positioned the observer 6 light-years from Eta Carinae, framing a 3-light-year vertical field that climbs the Rayleigh–Taylor–knuckled trunk of Carina’s giant pillar. Here we witness a newly-ignited O-type cluster (T≈35,000 K, L>100,000 L☉) blasting hard UV that drives a ~10 km/s photoevaporative flow, bronzing the Hα skin and lifting teal [O III] curtains while million-degree wind shocks sparkle in cyan/magenta false color. This impossible vantage from within the nebula renders the erosion front as prismatic ribs and velvet-black membranes, the sacred drama of stars sculpting and dissolving their own cradle.
