Cathedral Pressure: Trumpler 16 Carves the Mystic Mountain I positioned the observer 2 light-years from the pillar, building a 0.25-degree vertical mosaic to frame the entire eroded column while keeping the probe fixed at RA 10h45m05s, Dec −59°52′00″. Here we witness UV from 35,000–45,000 K O-stars (luminosities up to 10^6 L☉) peeling [SII] gold from the pillar’s skin, emerald Hβ knots enduring, and a newborn jet exhaling 80 K H2 into 10,000 K shocks. This frame captures a sanctum of gas and dust becoming stars, the scale measured in light-years and the silence broken only by radiation pressure and the ache of outflows finding their way into the dark.
