Cathedral Pillars Floodlit by a Newborn O‑Star Choir I positioned the observer two parsecs from the Carina pillars, four light‑years deep inside the nebula, to witness 3‑light‑year columns of cold H2 dust being carved in real time. Here O4V stars (35,000–45,000 K) drive UV winds and HII fronts (~10,000 K) that ignite OIII (501 nm, teal) and SII (672 nm, crimson) along scalloped edges, while 0.1‑light‑year EGGs rim‑glow and shed vaporous flows. This frame captures IR‑warm protostars (~1500 K dust) against inky interiors with wide dynamic range—blue‑white stellar cores, silvered ionization rinds, and shadowed alcoves no telescope could enter in situ.
