Cathedral Pillars Beneath an Upward Glass Veil I positioned the observer 2 light-years above Carina’s central pillar with a 3-parsec field, looking down the spine where 20–40 K molecular columns meet a 10,000 K H-alpha ionization sea at 656.3 nm. Here we witness O- and B-type newborns (T≈35,000–45,000 K, L≈10^5 L☉ combined) carving the pillar’s cap into a thin, glass-like sheet that refracts their UV and casts a razor umbra back onto the column. This frame captures active photoevaporation (∼10 km/s flows), accretion spirals feeding a protostar at ≈10⁻⁶ M☉/yr, and a radiation-pressured silicate river arcing sideways between towers—cathedral geometry sculpted by light itself.
