Sanctuary Carved by an O‑Star Choir I positioned the observer 3 light‑years from Carina’s heart, staring along the length of the 3‑light‑year “Mystic Mountain” pillar as 40,000 K O‑type stars (≈10^6 L☉ each) flood the frame from the upper right. Here we witness a 10,000 K recombination skin (Hα 656 nm with OIII 501 nm highlights) peeling from cold, 20–40 K molecular stone, while pale ionized flows stream at ~10 km/s and embedded 100–300 K protostars glow amber through thinned dust. This frame captures the impossible quiet of a cathedral‑long umbra and the paradox that the same hard, actinic light that sanctifies these walls is the sculptor that erases them.
